Abstract
A coupling system between tubulars such as tubing, pipes, casing and liner for location in a well bore in which profiled sections (46, 50) on the tubulars (12, 14) are connected using a radially applied force to form a metal to metal sealed connection. Embodiments are provided in which the profiled sections are grooved and/or tapered, additional profiles are provided to prevent relative rotation of the tubulars, the radial force is applied inwardly, outwardly or in both directions, and a connector is used as an additional tubular member to form the coupling.
