Claim:
1. An angular diffuser sector for a turbine engine compressor, the sector comprising: an inner shroud; an outer shroud; at least one vane extending radially between the shrouds and connected thereto via radial ends thereof; a casing element mounted at least in part around one of the shrouds, said casing element having an open groove entirely formed in the casing element facing an axial end of the corresponding shroud; a wedge-forming fitting interposed radially between the casing element and the corresponding shroud, the wedge presenting a first surface for coming into contact with a bearing surface of the axial end of the corresponding shroud, the bearing surface presenting a radial support, and a second surface that is inclined relative to the first surface and that is to come into axial contact with a corresponding sloping surface of the groove in the casing element; and elastic means for exerting an elastic axial force between the wedge and the casing element so as to keep the first surface in radial contact with the bearing surface and the second surface in axial contact with the sloping surface of the groove in the casing element.
