PROBLEM TO BE SOLVED: To provide a device comprising a rotor disk 6, and having a plurality of slots 12, and a flange 16 extending radially outwards, cooperating with a bearing surface of the disk to define a groove 18 that is open radially outwards. SOLUTION: This device comprises a plurality of blades 4, each having a root part 4a mounted in a slot of the disk. Each blade root part has a respective radial bearing surface. The radial bearing surface corresponds to the bearing surface of the disk, and has at least one nib part 20 extending radially inwards over the bearing surface to define a notch 22 that is open radially inwards, and a retaining ring 24 that is mounted in contact with the bearing surfaces of the disk and the blade root parts. The retaining ring is housed in the groove of the disk, held outwardly in the notches of the blade root parts, and constituted by a plurality of angular segments placed end to end.
