The invention relates to a device for the sealed coupling of two abutting cylindrical pipes, of the type that comprises a truncated surrounding sleeve (2) and clamping means which can reduce the apparent diameter of said sleeve. The surrounding sleeve (2) is cut longitudinally along the centre to form a slit (6) having: two hollowed-out central wedges (8) which are joined to the surrounding sleeve by a neck piece (9) and the base of which can be deformed in a controlled manner in order to connect pipes having different diameters; and two triangular housings (7) on the opposite side, in which the triangular wedges are housed when the sleeve is clamped to the pipes.
Cette invention concerne un dispositif de couplage étanche de deux tubes cylindriques adjacents, du type à manchon d'enrobage (2) coupé et à moyens de serrage pouvant réduire le diamètre apparent. Le manchon d'enrobage (2) présente une découpe longitudinale centrale (6) de manière à former une encoche (6) pourvue de deux cales centrales creuses (8) déformables à la base de manière contrôlée pour s'adapter à des tubes de différents diamètres; chaque cale étant reliée au manchon d'enrobage par un col (9). Le manchon présente également deux logements triangulaires (7) ménagés dans la partie opposée et dans lesquels s'insèrent les cales triangulaires au moment du serrage.
