The device has a stop ball knob (24) and a stop piston (28) that are displaceable using a dead center overshoot arrangement (32). The arrangement comprises levers (34, 36) that are connected at one of their ends by an articulation core (38). The levers (34, 36) are connected at their other ends to a base (40) and to the stop piston, respectively. The lever (34) is elastically deformable in its longitudinal direction.
