Abstract

L’invention concerne un ensemble comprenant un bossage annulaire présentant une face interne et une ouverture et s’étendant selon un axe longitudinal X. L’ensemble comprend en outre une bague anti-usure qui comporte un corps annulaire qui est solidarisé avec le bossage et qui recouvre la face interne, le corps annulaire s’étendant entre une extrémité distale et une extrémité proximale qui se situe au niveau de l’ouverture, la bague comportant un relief qui s’étend depuis l’extrémité proximale hors du bossage, la bague étant apte à être désolidarisée du bossage par une action sur le relief.
