ABSTRACT:
A system comprises a plug locking assembly and a key. The plug locking assembly comprises a cover for receiving and holding a plug comprising a latch and a latch support surface positionable under the latch. A rotatable cam comprising a stop surface and a slot may carry the latch support surface and may interact with a cam latch comprising an arm. The arm is alternately positionable to abut the stop surface and to lie within the slot. The key may comprise a shaft, a key tab and a limit tab. The key mates with a key receiving member associated with the cover. The limit tab is positioned on a top surface of the shaft and helps prevent over-rotation of the latch support member.
