DEVICE FOR TWO BARE PIPES' TIGHT CONNEXION

摘要

Leaktight coupling device for two smooth equal-diameter tubes arranged end-to-end, especially for the coupling of two parts of an engine exhaust pipe, such as those of motor vehicles. A one-piece sleeve (1) comprises a longitudinal slot (2) with two radial assembly lips (3), and surrounds the opposing ends of the two tubes on which it is clamped by means of a screw or bolt (7) passing through the radial lips. The sleeve (1) has two frustoconical ends (1b) located either side of a cylindrical middle portion (1a) intended to straddle the point of connection of the two tubes and each lip (3) of the longitudinal slot (2) comprises at least one stiffening part (5) extending between said lip and each of the corresponding frustoconical ends of the sleeve. ……
