The clutch has a housing (2) for the disengagement mechanism, (100) with a fixed guide tube (4) for a shaft (101), surrounded by an annular chamber (40) containing a control fluid and a piston (3) equipped with an actuator (11) for the disengagement mechanism. The guide tube and chamber are made from concentric inner (407) and outer (405) tubes, connected by a base (41) and produced by impact extrusion from a metal, especially aluminum, blank. The base is thicker than the inner and outer tubes and is connected to them by rounded surfaces.
