Abstract
A holding device for locking the head of a syringe piston on a pusher has arms connected to respective pinions pivotable and translationally displaceable so that the corresponding arm is involved in the same motion between a rest position, in which the arms are closed and pressed against the pusher, and an open position, in which the arms are opened and remote therefrom, the translation is carried out prior to rotation during the movement toward the open position or in reverse order toward the rest position. The holding device also has a control member and means for converting a part of the control member movement by transmitting it to at least one pinion as a translation movement, which are translationally locked, and means for converting a part of the control member movement by transmitting it to at least one pinion as a rotation movement.
