Any locking IECs that I can install on an amp?

I asked the same question a while back, you'd figure in the audio and computer industry such a device would be available by now. (don't think it be too difficult to manufacture now days)
They'd sure be useful with todays larger-than-garden-hose AC cords for us audio heads !
Locking connectors on balanced interconnects and digital cables work very nicely.
Good luck Pete, maybe someone can help us both out here !
