Abstract

L'invention concerne un dispositif de fixation doté d'un élément de fixation comprenant une partie de tête et une partie de corps allongé fileté s'étendant axialement à partir de la partie de tête. Le dispositif de fixation comprend également un rondelle-frein et un écrou freiné fileté destiné à s'accoupler de façon tournante avec l'élément de fixation. La rondelle-frein présente une surface inférieure à partir de laquelle s'étend une pluralité de dents de rochet. La rondelle-frein est configurée pour se coupler à l'élément de fixation en vue d'un mouvement axial mais est immobilisée en rotation. L'écrou freiné fileté présente une surface supérieure définissant au moins un bras de cliquet. Le bras de cliquet comprend au moins une dent de cliquet destinée à interagir avec au moins une dent de la pluralité de dents de rochet, et une bride s'étendant radialement au-delà du bras de cliquet.
