ABSTRACT:
A device is disclosed for hermetically coupling two smooth tubes of the same diameter disposed end to end, particularly for coupling two elements of the exhaust pipe of an engine, such as those of automobile vehicles. A bush in one piece comprises a longitudinal slot provided with two radial assembly lips and surrounds the opposite ends of the two tubes on which it is clamped by a screw or a bolt traversing the radial lips. The bush presents two frusto-conical ends located on either side of a cylindrical central portion intended to be mounted astride the zone of connection of the two tubes and each lip of the longitudinal slot comprises at least one rigidifying element extending between said lip and each of the corresponding frusto-conical ends of the bush.
