Abstract: A first pipe end is crimped (contracted) over one end of a second pipe inserted telescopically into the first pipe end by two compressing jaws having opposed semi-cylindrical concavities of equal radius of curvature equal to the outer radius of the first pipe end after crimping, whereby a uniform, leakproof contact pressure, due to elastic reaction, is established between the contacting surfaces.
