My school had a way to keep peripherals from wandering off, but if all you need to do is swap the cables then I’m not sure that would still work. Wrapping the cables into a wiring loom makes that process slower, assuming the loom is complicated enough. Did you ever use heat shrink? Or locking cable ties?

What the school did was run a steel cable behind the desks, then put a loop of the mouse chord through a steel washer and ran the security cable through all the loops. If you secure both ends you can’t get the cables separated even with slack.

The trick is that the hole in the washer had to be smaller than the connector so you couldn’t fish it back through no matter how much slack you get. That could still work for USB-A, but these days the connectors are getting smaller than the diameter of curvature of the cable, so you’d break it trying to do this. And on many peripherals you could destroy the chord without reducing the value of the device. One could cut the cable and install this Trojan one on many devices these days, the only telltale would be that the cable isn’t routed properly, which might be harder to notice immediately.
