ABSTRACT:
A device for holding an annular end plate against a radial face of a rotor disc, the disc having in the radial face an annular recess behind a collar extending radially outwards, and the end plate having, in its radially inner part, an annular base bearing against the radially outer wall of the recess and a foot extending radially inwards in the recess from the base, the device including a split annular retaining ring disposed in the recess. The ring is constituted by a snap ring interposed axially between the foot of the end plate and the collar and the peripheral surface of which butts against the base, the peripheral surface and the collar comprising, when joined, notches, which open radially outwards and are intended to receive compression tools for the snap ring, which tools retract into the contour of the collar during the assembly or disassembly of the end plate.
