Abstract
A declutching device for a clutch of the pull-off type, especially for a motor vehicle, comprises an hydraulic actuator, a preloading coil spring which permanently biasses the movable member of the hydraulic actuator towards its retracted position into the fixed member of the actuator with which the movable member is in piston and cylinder relationship, and a retaining element for holding the movable member in its extended position with respect to the fixed member until the declutching device has been properly snap-fitted on to the clutch. The preloading spring is indexed angularly on the fixed member and on the movable member, and the retaining element comprise a lug, which is fixed to one of the two actuator members and engages with an angle element fixed to the other actuator element, so as to provide axial and circumferential abutment between the two actuator members in a predetermined relative angular position of these latter, and such as to put the spring into torsional prestress.
