Re: Power Cables...
(latching IEC cables)
Unfortunately these don't hold the plug in, but they do stop stuff coming out of the back of the computer.
You can get PDUs with latching IEC sockets too:

There are also friction sleeves for PDU C13 sockets to stop them popping out (APC ones are terrible for this) - https://www.tripplite.com/c14-plug-lock-insert-for-c13-outlets-blue~PLC13BL/ - they're a bitch to use but they do stop accidental unplugging and they're cheap.
Click-locks grab onto the earth pin and don't require a special plug or other malarky like virtually every other kind of locking connector does. They can be pulled out without releasing the grip, but it takes a hell of a pull. http://www.ieclock.com/videos/?slug=how-it-works--iec-lock-outlets
These really are bloody useful when fitted to a PDU in the back of a rack or other cramped enclosure. It's just a pity you can't get locking 13A UK sockets.
