Abstract: A device is provided for protectively enclosing coupled terminals of mated industrial gauge electrical cords. The device, which can accommodate terminals and cords of varying size, easily creates a water-impervious shield encompassing the coupled terminals. The device is comprised of a flexible sheath having two longitudinal edges interengageable by a zipper to form a tubular structure. Binding straps disposed upon the exterior surface of the sheath adjacent each tubular extremity apply compressive force to underlying sealing bands which grip the electrical cord.
