ABSTRACT:
A connection for tubulars includes an outer housing, an inner housing receivable in the outer housing, a retainer member coupled to and axially restrained with respect to the inner housing, and a slidable member mounted on the inner housing and movable between an engaged position and a disengaged position. The slidable member carries a plurality of engagement elements that form an interlocking joint between the retainer member and the outer housing when the slidable member is in the engaged position.
