Abstract

La présente invention concerne un mécanisme de fixation provisoire qui permet d'obtenir une fixation provisoire fiable au moyen d'une opération simple. Un mécanisme de fixation provisoire (20) comprend : un élément de guidage (25) qui est inséré dans une rainure de goulotte d'une goulotte guide-fils ; un élément à cliquet rétractable (24) qui a une partie de pointe qui fait saillie vers la gauche ou vers la droite à partir de l'élément de guidage (25) ; et un ressort de compression (moyens de sollicitation) qui sollicite l'élément à cliquet (24) dans la direction de saillie. Lorsque l'élément de guidage (25) est inséré dans la rainure de goulotte par le dessous, l'élément à cliquet (24) se rétracte suite au contact d'une première partie de la rainure de goulotte avec la partie de pointe et il fait ensuite saillie après que la partie de pointe a traversé la première partie de la rainure de goulotte, ce qui amène la partie de pointe à venir en prise avec le goulotte guide-fils.
