Abstract
The invention proposes an aeronautical turbine engine assembly comprising an upstream casing () to which guide blading () is fastened, and a downstream casing () to which a sealing element () provided with an abradable material for rotor blading is fastened. This assembly further comprises a shroud ring () placed between the upstream casing and the downstream casing and fastening means () for detachably fastening the shroud ring. In order to be fastened to the upstream casing, the guide blading () of the turbine engine is mounted on a downstream hook () of the upstream casing, without being hooked onto the shroud ring (), and the downstream casing () has an upstream hook with which the sealing element () is engaged in order to be fastened to the downstream casing, or the shroud ring has an upstream hook on which the sealing element () is mounted so as to be fastened to the downstream casing.
