Apparatus and method for connecting tubular members in a wellbore. A host tubular member has annular members mounted within a receiving section to provide regions of differing resistance to the radial load. When a portion of a second tubular member is expanded radially outwardly within the receiving section a joint is formed between the members. Embodiments of host tubular members are described including recesses for the portion to form protrusions within, collapsible rings, channels and valves to expel fluid from the interface between the members and gripper elements and sealing elements to improve the joint. |
