Abstract
A power cord connector engages a power outlet of the two wire or three wire types. The connector (plug) has a pair of spaced apart prongs in side by side parallel alignment and a grounding pin which is slidingly mounted within a recess in the connector body so as to be positionable between an extended position in parallel, spaced apart alignment with the prongs, and a retracted position fully enclosed within the recess. A biasing spring is positioned within the recess for urging the grounding pin into the extended position. A locking device includes a finger actuatable slide engaged with a tongue spring enabling the tongue to be moved into a locking position inhibiting retraction of the grounding pin.
