Abstract
A device for axial locking of a moving part in rotation with respect to a reference part, includes a downstream locking wedge provided with lugs laid out such that the downstream locking wedge can be placed in: a first angular position in which the downstream locking wedge may be translated axially with respect to the moving part, a second angular position in which the lugs axially immobilize the downstream locking wedge with respect to the moving part; an upstream locking wedge able to prevent the rotation of the downstream locking wedge with respect to the moving part; and a stop segment able to immobilize axially the upstream locking wedge against the downstream locking wedge.
