DEVICE FOR THE SEALED COUPLING OF TWO CYLINDRICAL PIPES HAVING DIFFERENT DIAMETERS

摘要

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.
