A device for retaining an electrical plug and extension cord to another plug and extension cord employs fastener strip elements secured to the cord adjacent to the plug by a circumferential clamping element. When the electrical plug is engaged with a corresponding socket, the mechanical fastener elements secured to the plug engage cooperating fastening elements affixed to the corresponding socket to retain the assembly in its connected state. The fastener elements may be mushroom-type fastener elements such as those available under the name Dual Lock.
