The spring seat (20) comprises a peripheral disc portion (32) and a central portion (28) provided with a central aperture (34) allowing the plunger (14) to pass therethrough and be positioned in a final position. The spring seat (20) further comprises a engagement aperture (34) enabling through engagement of the extremity (18) of the plunger in a preliminary engagement position distinct from the final position, said engagement aperture (34) opening into the central aperture (34) so that the plunger (14) can be moved from the engagement position to the final position.
