Abstract

Une structure de clef comprend une tige (6) comportant une extrémité distale formée avec une tête d'entraînement (60) ayant une périphérie intérieure, et une pluralité de saillies de maintien (61) formées chacune d'une seule pièce sur un côté de la périphérie intérieure de la tête d'entraînement (60). De cette façon, lorsque la tête d'entraînement (60) de la structure de clef est montée sur une tête, les saillies de maintien (61) sont disposées de façon stable et rigide sur la tête, de façon à empêcher par conséquent la tête d'entraînement (60) de se détacher de la tête.
