Abstract
A method and apparatus for joining two tubular members in a strong, leak-proof fashion in which a band of ductile metal is passed around the adjacent ends of the members and circumferentially stressed beyond its elastic limit to conform intimately with the outer surfaces of the members throughout practically their entire circumstances. Several constructions for applying the circumferential forces are disclosed, and use is taught of a packing element to prevent paraxial or helical leakage.
