Block anti-noise for stiffening beam of a vehicle door

The wedge (5) has a longitudinal slot (7) spaced elastically from the wedge when a threaded end of a stud (6) is engaged across the slot such that slot edges cooperate with threading grooves of the stud to hold the wedge on a reinforcement beam (2) of a door at an adjustable height. The wedge is maintained in a lower part of the beam, opposite to an upper part indexed by the stud, by a wiring harness (8) integrated to the door.
