Abstract
A coupling, comprised of a tube with an attached tubular shell, for attachment with external components. The tube has a first end, second end and a longitudinal bore extending therethrough. The tube further includes an intermediate portion between the first and second ends having spaced radially outwardly extending annular beads. The tubular shell has a first portion axially confined between the annular beads and has an inner surface with a first axial end and a second axial end, wherein one of the first and the second inner axial ends has a non-rounded shape. The shell has a second portion extending axially from the first portion to a free end and has an inner surface spaced radially and coaxially outwardly of the exterior of the tube second end to define an annular recess therebetween and is adapted to be inwardly deformed toward the tube second end.
