It is preferable that the cross section located in each has a cross-shaped axial part. In this case, the elastic engagement leg can be easily bent due to the presence of the cross-shaped space. Therefore, the insertion force to the attached member can be reduced.

Abstract

L'invention porte sur une agrafe dotée d'une partie tête qui comprend une partie bord et une partie collerette, et une partie pied suspendue à la surface inférieure de la partie tête et ayant une branche de prise élastique munie d'une partie de verrouillage qui, lorsqu'elle est enfoncée dans un trou de fixation formé dans un élément qu'il s'agit de fixer, attaque ledit élément qu'il s'agit de fixer entre ladite partie de verrouillage et la partie collerette. Etant donné que la périphérie de la pointe de la partie collerette est épaisse, l'étanchéité entre la partie collerette et l'élément à fixer peut être améliorée.
