  • Patent number: 4414711
    Abstract: My invention consists of a single unitary shaped resilient rod formed with an open eye section at one end of the rod of a size to detachably fit permanently about a flexible electrical cord near the attachment plug of the cord. The rod extends at right angles to the attached cord for a first distance and then extends a second distance at right angles to this first distance for a length generally of the length of an attached plug and socket assembly. The rod then extends along a diagonal axis towards the cord to terminate in an open S or Z shape of a size to permit wrapping about a second flexible electric cord attached to a socket joined to the plug of the first cord. The invention thus serves to prevent disengagement of the plug from the socket, and prevents separation of two attached electrical cords.
