The stator is made of ceramic matrix composite material and comprises: a bladed hub carrying blades with a radially projecting finger at the end of each blade; and two toothed rings having teeth facing one another with the rings being urged towards each other in order to hold each tenon of a blade both axially and circumferentially between a flank of one of the teeth of one of the rings and a flank of one of the teeth of the other ring. The rings are urged towards each other by resilient means which enable them to move apart from each other with the two rings also rotating relative to each other under the effect of the blade tenons expanding, with the stator being fixed to the casing of a turbojet by mechanical connections between the casing and one of the rings.
