Abstract

La présente invention concerne un dispositif de fixation comprenant: un boîtier (12); un élément d'insertion (1) qui est disposé dans le boîtier (12), peut coulisser, et présente un orifice (2) et des éléments sphériques (5) disposés pour pouvoir se déplacer transversalement à l'orifice (2); un élément de maintien (6) qui présente une surface intérieure conique et qui entoure l'élément d'insertion (1) au moins par endroits, les éléments sphériques (5) venant en butée contre ladite surface intérieure conique; des éléments de rappel (9) qui servent à faire appuyer l'élément d'insertion (1) contre l'élément de maintien (6), de façon sensiblement parallèle à l'orifice (2); et une pointe (10) qui peut être insérée dans l'orifice (2) depuis l'extérieur et qui peut être maintenue dans l'orifice (2) par les éléments sphériques (5) par liaison de frottements. Le dispositif de fixation présente au niveau de l'extrémité de l'élément d'insertion, opposée à l'ouverture d'entrée de l'orifice (2), une gorge (18) qui entoure au moins partiellement le côté extérieur de l'élément d'insertion (1). Le dispositif comprend en outre un élément de rappel (15) de préférence plat qui s'encliquette au moins partiellement dans la gorge (18). La compression latérale de deux bords opposés de l'élément de rappel (15) l'un vers l'autre, permet d'arquer ce dernier vers le haut et ainsi de tirer l'élément d'insertion (1) vers le haut, ce qui a pour conséquence de supprimer la liaison de frottements entre la pointe (10) et les éléments sphériques (5).
