<p>A joint is formed at adjacent ends of tubes (5, 7) by inserting the ends of the tubes into opposite ends of sleeve (1) until the tube ends engage centrally positioned inwardly extending protrusion (3). The sleeve (1) is crimped inwardly into frictional engagement with the tubes (5, 7), only at the middle portion and at the end portions of the sleeve to partially deform the sleeve and the tubes at the adjacent ends of the tubes and at positions of the tubes displaced from the tube ends.</p> |
