First Claim
1. A coupling for connection of a tubular member, the coupling comprising:
- a coupling housing which includes a first end into which the tubular member is inserted and a second end which is located opposite the first end;
a clamping ring which is positioned in the coupling housing against a first conical surface;
a sealing ring which is positioned in the coupling housing; and
a return ring which is positioned in the coupling housing between the clamping ring and the second end adjacent a second conical surface that is tapered opposite to the first conical surface;
the return ring being expandable and comprising a central aperture which is smaller than the external diameter of the tubular member;
wherein when the tubular member is inserted into the coupling housing and forced through the return ring, the return ring will expand radially outwardly and move along the second conical surface in a direction opposite to that of the tubular member.

Abstract
A coupling for connection of a tube comprises a coupling housing which includes a first end into which the tube is inserted, a clamping ring which is positioned in the coupling housing against a first conical surface, a sealing ring which is positioned in the coupling housing, and a return ring which is positioned in the coupling housing between the clamping ring and a second end of the housing adjacent a second conical surface that is tapered opposite to the first conical surface. The return ring is expandable and comprises a central aperture which is smaller than the external diameter of the tube. Accordingly, when the tube is pushed into the coupling housing and forced through the return ring, the return ring will expand and move along the second conical surface.
