How to secure laptop external connectors (USB, Ethernet, DisplayPort\HDMI, audio)?
First, I love this forum, I just found it and already got a few issues I've run into worked out, written the ideas down, and set some space in my testing area to try them out.
Second, I do mostly smaller office setups and upgrades, so a lot of my work is handling the simpler day to day of the home office, small reception desk or similar.
This problem is one I've dealt with myself, as well as in offices I work for. I've even tried similar fixes to what I found here, and some commercial ones that were much more expensive for more function than needed. The question is a simple one and shows up in many flavors, so I worked it to make it fit most, if not all, of them.
How do you secure an external connection wire to your laptop so it doesn't loosen or wiggle and either lose connection or damage the port? There are a lot of answers for different situations:
Use a professional product like the Smart Keeper wire lock to hold the plug to the port (a small clamp in the lock grips the physical port, and a hart jolt could damage the port horribly; it's also costly, just under $40 US on Amazon without the "Key" that unlocks the plug).
Use some hot glue to hold the usb in place (while it will take most minor jolts in stride, a good jolt or jock will break the seal and you won't see it, but you can always reapply; best as a short term solution where there's not a lot of "pull" in any one direction; too much pull will break the seal and could damage the port or put glue dust inside the body of your laptop).
magnetic or clamp wire locks\anchors (these work well for brand new ports, but those that have seen much use and have been widened by that use are unlikely to see much benefit, especially with flimsy usb; they can also be costly at around $10 for a single anchor or closer to 15 for a multi wire anchor)
(This is a new one I tried and a bit of a diy project, but it's less costly and does provide enough grab for connections and holding in place without damaging ports, while being easier to remove; however, to prevent pulling on the port in some situations, you need to be careful in removal and relieve the pressure by holding the wire with one hand as you remove the grip with the other)
- Velcro X plug grips; You can make these yourself, I haven't seen any of these premade anywhere, not even online;
First, you need to get some hook and loop velcro with extremely good adhesive backing, or you could just use a cheap roll that has hook on one side, loop on the other and then use superglue or alientape to hold it in place [use a really strong hold] and you'll put a strip right next to your keyboard on a laptop, just barely away from the edge where your ports are located or the closest convenient flat spot on a tower, from just below any power and monitor button all the way down to an inch or two beyond your last side port; next you need to put another strip on the bottom of the laptop, again, right along the edge, and line it up with the other one [because I used double sided cord organizers designed to roll long power cords, it didn't matter which I used for the computer top\bottom; if you make your own cable grip from a cheap double sided roll as I've tried, use the same hook or loop for both top and bottom and make sure you do the next part correct]; if you want to make a wire grip for your hook\loop anchor, you can use cord organizer wraps like I have [I needed at least two for each wire, you could use 3 or 4 to go two directions top and bottom], or you can simply take a double sided roll of velcro hook and loop, a 1\2 inch will work, you may cut this in half etc, then you cut a length long enough to go from the back of the plug where the wire begins to a little past the anchors on BOTH top and bottom [the plug should be somewhere in the middle of the length], then you cut a slit longways in your velcro strip at the center of the length that is wide enough for your plug to slide through [not short ways because some plugs will be longer than your velcro strip is wide], and slide your wire through, then use superglue or a small strip of velcro to close and lock the slit around the wire; you can stop here or further lock the velcro in place by gluing it to aft reinforcement on the plug, you shouldn't have to; I recommend using at least two of these on each wire in an X pattern; why is this so functional? Even if you have a ton of wires for a laptop, using a double sided length of velcro to pull the wire into place lets them all overlap one another without losing the function. If you find the need, you can glue wider pads to the tips of each length for greater hold, and when using them, use a slight angle to provide dual directional support. With ports closer together, you could anchor one in an X pattern [if you were looking directly into the port, the slash lines of the X are the velcro lengths], then use only a \ or / pattern [realistically, one should angle one way on top, and the other way on the bottom] on the next while also anchoring it to the first wire using the remaining velcro length; Using the X pattern on the two outermost ports on any side provides two full anchors you can then build half anchors onto without complicating one another, just be sure you have angled the main anchor properly. Double sided rolls work best for this if you can find some decent adhesives strips or a glue you think will work because you can use another length from the same roll to cover your slit for your plug and lock the velcro length around the wire where the wire meets the usb plug casing, as well as create longer pads for the tips where the X lengths meet the anchor points, both without using any glue, and it allows you to remove these for use with another wire. With Cord wraps, you'll need at least 2 per wire, 4 for full anchor and you won't need to cut slits as they usually have a small slit at one end of each wrap that allows you to lock it onto the wire; they can be cut down to length afterward and the excess can be used for longer end pads for stronger hold. All of these will have a tendency to stretch a little over time, but you can just alter your angle on the X to fix it, and they are easily redone once anchor points are in place.

How do you secure an external connection wire to your laptop so it doesn't loosen or wiggle and either lose connection or damage the port?
"Laptop" implies a mobile device. Those cables need to be unplugged and re-plugged as needed. If a cable comes loose, give it a wiggle.
If the device does not need to move, deploy a lower-cost desktop or mini-PC.
Regardless of the device type, I'd have to ask why cables are coming loose in your environment frequently enough that this is a problem.
Is this an office environment, or some kind of an industrial manufacturing floor with high vibration?

holy run on sentences batman.
I rather go back to reading the AI posts here. At least they add line breaks.
Also, they make these things called desktops.

You don't. It's a laptop. It should have a docking station and a single plug at most and it should absolutely be removable. Because it's a laptop. Its purpose is to be portable.
If you need something with secured plugs you lock a tower in a cabinet.
Though I'll be honest. I didn't read that book.

Stop trying to fill an operational problem with a technical solution.
Train people not to abuse their equipment and you’ll be fine. The only time we ever see issues with connectors are ham-fisted users that treat stuff without a care in the world. Any time we need to RMA to vendor or replacement completely, we keep the manager and the business navigator informed. They can do what they want with the information.

You seem to have a requirement to physically tether a mobile device (laptop) to a physical desk or install? Otherwise it makes little sense to place persistent cable retainment stuff in place for a device that is intended to be docked/undocked/moved around etc. etc.
The laptop solution for this is a proper docking station where you can bind all the cables to the docking station and still let the laptop be taken away and placed back

The answer is you don't, this isn't really a problem with a typical clean setup. There are those cable grippers that you can install on desks, and they help route cables neatly. This can help ensure cables aren't straining the ports by being pulled sideways.
You can reduce the amount of connected peripherals utilizing wifi, wireless mouse, and wireless keyboard - or have users use the built in keyboard but I don't recommend that for everyday users.
Ultimately though you'd plug those things into the dock and just plug/unplug the dock, which may use one or two USB-C ports. Then you only have to worry about securing the dock to the table (maybe) and ensuring the dock cable(s) connect satisfactorily.
You can maybe replace laptops with thin desktop clients if there is truly no need to move them around. This always seems objectionable but I think it's a choice idea. You can mount them out of the way or sometimes as an AIO type setup, run all the cabling out of the way. If a user moving a keyboard on their desk in a reasonable work area is damaging a port, that's a layout/physical install issue not something to lock the port with.

In normal usage, cables and jacks (usb, audio connectors, etc) should not be yanked on. If it is a single user having repeated issues, it sounds like a training problem.

Honestly, for small office setups where you're dealing with worn ports, I've had the best luck with simple cable strain relief rather than trying to lock the connector itself.
Velcro cable ties anchored to the desk (not the laptop) work well. Route the cable so there's a service loop with slack before it reaches the port. That way any tugging pulls against the desk anchor, not the connector.
For laptops that move around, a small binder clip on the cable about 6 inches from the plug, clipped to whatever surface edge is nearby, does the same thing.
Your DIY velcro system sounds solid but maybe overengineered for most cases tho?

You must put silicon paste between your hard drives as an emergency measure.
The thing to protect the integrity of your machines is to open them up and wrap aluminium foil around the inner works, then just put them back together.
Then smear vegetarian butter or low quality margarine (this key point!) all over your head and finish it up with aluminium foil. Make it as tight as possible, but remember you must be able to breathe. N95 mask will tremendeously or even completely null your efforts and potentially kill you.
If you don't have vegetarian butter available, try peanut butter and well chewed bubble gum. Way more expensive and not quite as effective. Sugar and chocolate in peanut spreads decrease the effectiveness even further, but it's better than nothing.
Good lück, cyber information highway samurai!

If they break the connectors they should be liable for damaging, simple as that. It's hard to break it unless you're being intentional with it

I can't tell if you're trying to fix a loose port or if you're worried your laptop is going to develop sentience and try to escape the desk.
Modern technology actually solved this years ago—it's called a docking station. You plug in one cable, and you don't have to ruin your machine with superglue and alien tape like you're building a trap in Home Alone.
