ABSTRACT:
A coupling of heat recoverable metallic material for joining tubular members and other cylindrical substrates. The couplings include a hollow member having at least one opening for receipt of a tube. This hollow member is designed to eliminate relative motion between the ends of the member and the tubing during flexure of the tubing and coupling assembly. This elimination of such relative motion is accomplished by incorporating thin-walled sections at each end of the hollow member with collars located outwardly of the thin-walled sections. The collars tightly grip the tubing to prevent relative motion between the collar and the tubing while the thin-walled sections allow flexural response of the coupling to the flexure of the tubing itself.
