A plunger is arranged inside the housing and is axially displaceable along the rotation axis “X”, wherein the plunger is configured to bring the anchoring means from their engaged position to their disengaged position and vice versa. The plunger is axially displaceable relative to the anchoring means between two stable axial positions at axis “X”, namely: a pushed-down position in which the plunger remains stable and force the anchoring means to their engaged or to their disengaged position, and a release position in which the plunger remains stable and in which the anchoring means are in the other position.
