The present invention relates to an apparatus to provide a secure connection between the male plug and female receptacle on adjoining electrical cords which prevent the plug from separating from the receptacle by forcing the plug and the receptacle together. The apparatus comprises a pair of opposing body portions (2), each of said body portions having an interior and an exterior end (3, 4). The body portions preferably consist of a pair of co-axial cones (2) with generally flat opposing bases (8). A centrally disposed longitudinal conduit (5) is provided through said body portions (2) and opens on said interior and exterior ends (3, 4) of said body portions. Elastic means (10) link said body portions so that said body portions are biased towards each other when said elastic means is stretched to separate the body portions. The elastic means preferably comprise a plurality of linking members (10) attaching the interior ends (3) of said body portions (2). The linking members (10) are preferably equi-spaced about the periphery of the interior ends (3) of said body portions (2) wherein the generally flat opposing faces (8) of said body portions are maintained in contact with said male plug and female receptacle. The linking members are preferably integrally molded with the body portions. Means (9) are provided to permit said electrical cords to be inserted into the longitudinal conduits (5) in said body portions (2) such that the male plug and female receptacle are contained between the body portions to prevent separation of the male plug and female receptacle. The means preferably consists of a longitudinal slit (9) in said body portions.
