A device for constricting an electric cable used underwater for restricting the flow of water lengthwise of the cable when its sheath is perforated intentionally or accidentally. The device comprises a rigid hollow cylinder which fits around the cable with spacing between the cable and the interior wall of the hollow cylinder and has an end wall with an opening for the passage of the cable through the hollow cylinder. The opposite end of the hollow cylinder has an exterior flange, and the space between the interior wall thereof and the cable is filled with an elastomeric or plastomeric sleeve. An annular body which fits around the cable and into the hollow cylinder so as to engage the sleeve has an external flange by which the body may be pressed into the hollow cylinder and thereby compress the sleeve and, hence, the cable.
