Abstract

L'invention concerne un élément de fixation qui est apte à empêcher des plis dans une feuille, telle qu'une feuille d'étoffe, lorsque la feuille est pénétrée par une section de tige. Un élément de fixation (80) pénètre dans une feuille (100) à partir d'un côté de surface de celle-ci et est relié à un objet (20) à fixer, l'objet (20) étant disposé sur l'autre côté de surface de la feuille (100). L'élément de fixation (80) comprend : un corps d'élément de fixation (10) comportant une section de base (11) et une section de tige (13) qui est disposée sur la section de base (11) ; et un corps entourant (30) qui est formé d'un seul tenant avec le corps d'élément de fixation (10) ou en tant que corps séparé d'avec celui-ci et qui entoure au moins partiellement le côté d'extrémité avant d'au moins la section de tige (13). Le corps entourant (30) présente une extrémité avant qui s'étend vers l'extérieur à distance de l'extrémité avant de la section de tige (13).
