Zusammenfassung:	The present invention relates to a positioning member (10) of a ring segment for a turbine wheel rotatably mounted about an axis in a housing. The invention is characterised in that the member has: an attachment portion (20) intended for being attached to the housing; a resilient portion (24, 26, 28) forming a spring; a support portion (30, 32) connected to the resilient portion and intended for engaging axially with the ring segment, such that, when said member is mounted, the ring segment is axially clamped against a portion of the housing by the positioning member. La présente invention concerne un organe de positionnement (10) d'un segment d'anneau pour une roue de turbine montée rotative autour d'un axe dans un carter. L'invention se caractérise en ce que l'organe présente : une portion de fixation (20) destinée à être fixée au carter; une portion élastique (24, 26, 28) formant ressort; une portion d'appui (30, 32) reliée à la portion élastique et destinée à venir en appui axialement contre le segment d'anneau, de sorte que, lorsque ledit organe est monté, le segment d'anneau est plaqué axialement contre une partie du carter par l'organe de positionnement.
