ABSTRACT:
Apparatus and methods are provided for coupling a body member to a cylindrical member having a radially outward extending shoulder thereon. A coupling includes the body member and an annular seal for sealing between the body member and the cylindrical member. A plurality of collet sections are disposed around the body member, each of the collet sections having an upper end connected to the body member and having a lower end adapted for engagement with a lower end surface of the shoulder of the cylindrical member. An outer sleeve is slidably disposed about the plurality of collet sections and is slidable relative to the collet sections between an open position wherein the lower ends of the collet sections may receive the shoulder of the cylindrical member therebetween, and a closed position wherein the body member is sealingly coupled to the cylindrical member.
