Zusammenfassung:The device for rotationally blocking a retaining ring ( 20 ) on a rotor disk ( 10 ) comprises: successive first ( 162, 262 ) and second ( 164, 264 ) blocking hooks of the disk ( 10 ), at least one cleat ( 302, 304, 306 ) of said retaining ring ( 20 ), arranged close to a split ( 24 ) in the ring ( 20 ). The position of said at least one cleat ( 302, 304, 306 ) on said retaining ring ( 20 ) is such that, when said retaining ring ( 20 ) is in place in a groove ( 22 ) situated in the rotor disk ( 10 ), said at least one cleat ( 302, 304, 306 ) is in abutment against said first blocking hook ( 162, 262 ), and the split ( 24 ) is covered by said second blocking hook ( 164, 264 ).
