Abstract
Apparatus and method for sealingly connecting tubular members in a wellbore. In a connector apparatus 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, an annular resilient band member is arranged in the recesses. The annular resilient band member is acted on by the portion of the tubular member during expansion and maintains sealing contact to the portion after expansion.
