A common, grounded three-conductor male electrical plug including in the grounded blade a spring biased catch for engaging the walls of a female receptacle and locking the plug in the receptacle. An aperture in the plug allows a non-conductive tool to move the catch against the spring bias and away from the walls of the receptacle to unlock the plug and permit removal from the receptacle.
