Abstract
Apparatus and method for sealingly connecting tubular members in a wellbore. In an arrangement where a portion of a tubular member is radially expanded into sealing contact within a second tubular member, and the second tubular member has circumferential recesses on an inner surface, a resilient member protrudes from a side wall of the recesses. The resilient member is acted on by the portion of the tubular member during expansion and maintains sealing contact to the portion after expansion.
