Abstract A device for preventing the accidental disconnection of electrical cords comprising a first section and a second section. The first section has a conical-shaped plug receptacle adapted to receive any of a plurality of different sized, commercially available electrical plugs and a detent slot for holding the cord affixed to the plug. The second section has a detent slot adapted to receive a second electrical cord having a mating plug thereon. An adjustable means connects the first and second sections together to thereby prevent the accidental disconnection of the plugs when they are in a mated position.
