Patent ID: 7887242

Claim:
A coupling for connecting a first tube end of a first tube to a second tube end of a second tube, the first and the second tube receiving a cable coaxially therethrough, the cable having an outside diameter and the coupling comprising: a tubular first body and a tubular second body aligned coaxially with the first body, each body having a first body end for connection to a corresponding one of the tube ends and a second body end disposed opposite the second body end of the other body and being axially moveably connected thereto, the second body end of the second body having an inner contact surface; and an annular resilient seal member aligned coaxially with the first and the second body, the seal member having a first seal end received in the second body end of the first body and a second seal end received in the second body end of the second body, and the seal member having in a free state an inside diameter greater than the outside diameter of the cable, whereby with the first tube end being received in the first body end of the first body and the second tube end being received in the second body end of the second body, and the cable being received coaxially through the first and the second tube, the second body is axially moveable relative to the first body between a first position of the bodies wherein the body second ends are axially spaced-apart a first distance with the seal member being disposed in its free state, and a second position of the bodies wherein the body second ends are axially spaced-apart a second distance and the contact surface of the second body end of the second body radially compresses the seal member into an energized state wherein the inside diameter thereof sealingly engages the outside surface of the cable, wherein the first distance is less than the second distance.
