  • Patent number: 4643505
    Abstract: A housing (18) is provided for maintaining the plugs (14, 16) of a pair of extension cords (10, 12) connected. The housing (18) includes first and second members (24, 26) which are connected by a hinge (28) along one edge. The interior surfaces (38, 44) of each of the first and second members (24, 26) include a series of grooves (54, 56) distributed along the length of the members. Retaining washers (30, 32) are designed to be engageable with the grooves (54, 56) to hold the plugs of a connected pair of extension cords in engagement. The provision of a series of grooves (54, 56) permits the housing (18) to be adapted for use with a wide range of plug lengths. The slots (88) in the retaining washers (30, 32) are designed so that the cable passing therethrough is slightly offset from the central axis to resist motion in the plugs.
