Abstract
A device for attaching ring sectors around a turbine rotor in a turbomachine is disclosed. Each of the ring sectors includes at its upstream end a circumferential rim being able to be held on an annular casing rail by an annular locking member, and at its downstream end a pressing part that can press axially against a fixed element of the turbine to prevent the upstream rim of the ring sector from disengaging from the locking member in the event of considerable wear of the rail.
