Abstract: The lining (1) includes by studs (2) mounted on a support (3), each being rigid with the support by reason of a mounting element and is characterized in thata) the mounting element (5) consists of a base (9) with a flange (13) with no axial symmetry,b) the support (3) consists of two metal plates, a rigid support plate (7) and a mounting plate (6) having orifices (10) in order to be able to grip the said flange (13) by reason of mechanical connections (8) between these two plates (6, 7),c) at least one of the plates (6, 7) displaying a deformation in such a way as to grip the flange and so achieve rotational locking of the stud (2).
