Abstract: Mutually mating cable contact members, on longitudinally aligned contact carriers, are surrounded by annular sealing portions of these carriers, which have annular sealing surfaces engaging each other. Said sealing portions consist of materials having different elasticities. A ring surrounds the sealing portion of greater elasticity and presses the sealing surface of this portion against the sealing portion of the other contact carrier. By the coaction of the ring with the sealing portions of different elasticities, the new connector remains water tight when submerged in deep water for extended periods of time.
