<p>The union (1) has a clamping ring (5) for clamping a metal corrugated pipe (2), and a screw-in-fitting (3) and a connecting nut (4) comprising thread regions fitted to each other. The ring is formed as a cylindrical ring that is deformable from the screw-in- fitting. The ring has an inner diameter (D2) that is identical with an inner diameter (D1) of the nut. The nut comprises a collar (16) as a stopper at an end (18) of the ring, where breadth (B1) of the collar corresponds to wall thickness (S1) of the ring, which is made of heat treated metal alloy.</p> |
