A tube union for coupling the ends of a pair of tubes which are butted together includes a sleeve and two swaging collars about the sleeve without other components. Grooves and lands in the sleeve mate with a tube which is deformed into the grooves as the sleeve is urged inwardly under compression. The rings are urged centrally towards the central position of the sleeve by a tool constituted by two housing members which each have several components. Torsional wrenching of the housing members screws the housing members together, causing the collars to deform the sleeve. Thereafter pins are removed from the one housing members and the wrench from the other. This permits separation of the housing members from the swaging collars. The tool can effect connection or assembly of different elements.
