Abstract
A sealing ring configured to be pressed against a rotor disc of a turbine stage for an aircraft turbomachine, the ring including a plurality of anti-rotation pegs which prevent it from rotating in relation to the rotor disc, each peg protruding axially from a ring body and including two opposite circumferential-end surfaces, respectively configured to be located facing two directly consecutive blades carried on the rotor disc. An axially opening slot passes radially through at least one of the anti-rotation pegs.
