Abstract

L'invention concerne un système de fixation permettant de fixer une pièce (11) sur un élément de raccordement (9) constitué d'un matériau renforcé par des fibres, en particulier pour un véhicule automobile. Ce système est pourvu d'un corps de base (1) sensiblement tubulaire et d'ailettes (5) radialement en saillie, au moyen desquelles le corps de base (1) peut être fixé dans une encoche de clavette (10) ménagée sur l'élément de raccordement (9) à la façon d'une liaison à baïonnette. L'invention vise à fournir un système de fixation pouvant servir à la fixation détachable d'autres pièces (11) sur des éléments en matériau renforcé par des fibres (9). A cet effet, selon l'invention, un élément fileté (4) est inséré dans le corps de base (1).
