1. An assembly for an aeronautical turbine engine extending about an axis and comprising:
an upstream casing disposed around the axis and to which a guide blading of a distributor is fastened, the upstream casing being followed axially, in the downstream direction, by
a downstream casing disposed around the axis, whereon a sealing element provided with an abradable material intended to be facing a mobile guide blading of the aeronautical turbine engine configured to rotate about the axis is mounted,
the assembly further comprising:
a shroud ring inserted, about the axis, between the upstream casing and the downstream casing, and
removable fastening means for fastening the shroud ring, the upstream casing and the downstream casing together, detachably,
for said fastening thereof to the upstream casing, the distributor is mounted on a downstream hook of the upstream casing, without being hooked to the shroud ring, and:
either the shroud ring has an upstream hook for coupling the sealing element for said fastening thereof to the downstream casing,
or the downstream casing has an upstream hook whereon the sealing element is mounted for said fastening thereof to the downstream casing,
wherein:
if the downstream casing has said upstream hook whereon the sealing element is mounted for said fastening thereof to the downstream casing,
then the shroud ring is devoid of the upstream hook intended for said fastening of the sealing element to the downstream casing.
