Locking barrel connectors...

Aren't those called BNCs? ;)

In one of my other lives, I see Power Poles used in a very life critical application. They are used to connect pads to Automatic External Defibrillators. In that application, the two poles (15A, red & white) are glued together rather than using the roll pin.
