Abstract
A coupling apparatus is provided for connection to a cylindrical member. The coupling apparatus includes a body member and an annular seal between the body member and the cylindrical member. A plurality of collet sections are disposed about the body member, and each collet section has a first end connected to the body member and a second end adapted for engagement with a downward facing surface of a shoulder of the cylindrical member. An outer sleeve is slidable relative to the collet sections between an open position wherein the second ends of the collet sections are held in a relatively radially expanded position and a closed position. A release device is operably associated with the plurality of collet sections and the outer sleeve for moving the second ends of the collet sections to their relatively radially expanded position upon sliding of the outer sleeve from its closed position to its open position. This release device includes a radially outer tapered cam surface on the outer sleeve, a plurality of cam followers, one of which is attached to the second end of each of the collet sections, and a follower surface defined on each of the cam followers for engagement with the outer cam surface of the outer sleeve.
