Abstract: The system retains a plate against a disk presenting in its radial face an annular recess defined by a plurality of walls, one of which is formed by a face of a flange, said plate presenting an annular base pressing against the radially outer wall of the recess and a root which extends from the base into the recess, said system including a split annular retaining ring disposed in the recess. In characteristic manner, said flange presents a top end of crenellated outline provided with at least one notch, said root is provided with a front rim of crenellated outline, having at least one mortise, and a rear rim between which rims there is formed an annular groove for receiving the ring which presents an axial tenon suitable for penetrating into said notch and into said mortise.
