Date Dec. 14, 1995A locking clutch includes a torsion damper (20) and a piston (21), the torsion damper (20) having an inlet part (40) fixed to the piston (21) and an outlet part (60, 160, 260). The web has support portions (65) for the circumferential ends of springs (50, 52, 53) acting between the inlet parts (40) and outlet parts (60, 160, 260). The inlet part (40) of the torsion damper (20) consists of a plurality of guidance plates (40) fixed to the piston (21). Each plate (40) has a central part (47) and two lateral wings (49) to define holding portions (41) for the springs (50, 52, 53) and support portions (45, 145) for the springs (50, 52, 53). The piston (21) has at its external periphery an axially oriented annular shoulder (28) shaped so as to retain the springs (50, 52, 53).
