Abstract
Apparatus for connecting a cylindrical first member to a second member which may comprise: a tubular body attachable to the second member and adapted to receive one end of the first member; a gripping assembly carried by the body and movable from a radially expanded position, in which one end of the first member may be axially received and displaced from the body, to a radially contracted position gripping the exterior of the first member and preventing its axial displacement from the body; an annular seal assembly carried by the body and movable from a relaxed position, in which one end of the first member may be axially received therein, to a compressed position, sealingly engaging the first member; and an actuating assembly carried by the body and operable to move the gripping and seal assemblies to their contracted and compressed positions, respectively.
