Abstract

L'invention concerne un dispositif de fixation (1) d'un rail de montage (19). Le dispositif de fixation (1) est muni d'un disque perforé (6) d'où partent à angle droit quatre butées (16, 17) qui traversent une fente (20) du rail de montage (19) et ainsi positionnent latéralement le dispositif de fixation (1) et le maintiennent bloqué en rotation. Les butées (16, 17) maintiennent en outre un écrou rectangulaire (8) en tant qu'élément de blocage arrière (9) s'insérant dans le rail de montage (19) dans le sens de la longueur. Une fois inséré dans le rail de montage (19), l'élément de blocage arrière (9) est mis en position transversale, de sorte qu'il vient bloquer le rail de montage (19) par l'arrière.
