Abstract
A device for maintaining an interconnection between male and female electrical extension cord plugs of a pair of extension cords. A generally elongate housing is provided having an upper half and a lower half which are hingeably coupled together along one edge in an axial direction. A latch is provided for selectively securing and maintaining the upper half and lower half of the housing together in an aubtting relationship, forming an enclosure therein suitable for enclosing an interconnected male and female extension cord plug. A first aperture at one end of the housing is sized to receive an electrical extension cord while retaining a first plug within the housing. A slideably mounted plug retaining bracket is utilized to retain a second plug within the housing and a ratchet arrangement of angled slots and teeth are utilized to permit movement of the plug retaining bracket toward the first aperture while restricting movement in the opposite direction, thereby maintaining an interconnection between male and female extension cord plugs after urging the second plug toward the first plug.
