ABSTRACT:
The invention relates to a device for the sealed coupling of two abutting cylindrical pipes. The device includes a truncated surrounding sleeve and clamping device to reduce the apparent diameter of the sleeve. The surrounding sleeve is cut longitudinally along the center to form a slit having two hollowed-out central wedges, which are joined to the surrounding sleeve by a neck piece. The base of the sleeve can be deformed in a controlled manner in order to connect pipes having different diameters. Two triangular housings on the opposite side, in which the triangular wedges are housed when the sleeve is clamped to the pipes.
