ABSTRACT:
A connecting apparatus for two tubular members including an adapter sleeve extending over the end portion of one of the members in a coaxial relationship therewith and adapted to abutt the end of the other member. A threaded nut means extends over the adapter sleeve in engagement therewith, and is adapted to threadedly engage the outer surface of the corresponding end portion of the other member to connect the members together. The adapter sleeve increases in cross-section in a direction towards the end of the one member to decrease the stress on the latter member accordingly.
