Abstract
The invention relates to an axial turbomachine stator (2) comprising an inner shell (28) with an annular row of openings; an annular row of blades (26); the said blades extending substantially radially through the said openings, respectively, and each comprising a cut-out (34) on the inside of the shell; at least one blade-retaining plate (36) inserted in at least one cut-out (34), with means of immobilisation of the said plate in the cut-out(s). The means of immobilisation comprise at least one tongue (38) with an end forming a support surface (40) in contact with a part of the blade (26) or of one of the blades (26) located radially directly above the corresponding cut-out.
