Electronic – How to retrofit a barrel (coaxial) power connector to make it locking

connectordcpower

Perhaps this is a bit more of a mechanical question then electronic, I hope it is not off topic. We have all seen the many electronics that use a barrel style DC power connector (I guess sometimes called Coaxial). I am wondering if there is a device that can retrofit this connector to make it a locking connector or to better lock it in place.

Specifically, I am hoping to find something other than locking down the cable itself, such as via a plastic loop affixed to the back of the chassis. That works ok but for my purposes I was hoping more for something that would literally lock the barrel connector into its socket. And again, I am hoping to retrofit existing devices, rather than cut cables / drill new holes.

Perhaps something that increases the friction already holding the barrel in place, such as some sort of small wedge or ring? Does such a thing exist?

A liberal amount of hot glue on the connector and device panel. This would hold against vibration or light pulling. This isn't for preventing brute force unplugging. Also doesn't have superglue propensity to run, possibly getting between conductors.
