A receptacle for the plug contains an aperture to receive the at least one prong, the aperture including a lateral enlargement to receive the projecting hook portion when the prong is inserted therein thereby locking the plug to the receptacle. Depression of the release button pivots the locking hook retracting the hook portion to unlock the plug from the receptacle.
