(4), which protrudes axially from the base of the bracket (3). The stop 4 is arranged close to the tubular part 2 and includes a height less than that of the tubular part (2) relative to the base of the bracket
(3). The difference (H') between the height (H) of the tubular part (2) and the height (H) of the stop (4) and the gap (d) between the tubular part (2) and the stop (4) enables the tubular part (2) to enter contact with the stop
(4) in use from a given radial deformation level of the tubular part (2), thereby increasing the rigidity of the tubular part (2).
