Abstract

La présente invention concerne un élément de fixation (21) pour une fermeture à glissière métallique comprenant : une tête de verrouillage (30) ; et une première moitié (32) et une seconde moitié (33) qui se ramifient et s'étendent à partir de la tête de verrouillage (30). Les surfaces de la première moitié (32) et de la seconde moitié (33) se faisant face sont pourvues de rainures de maintien (39) formées le long de la direction de la largeur de l'élément de fixation. La ramification de la première moitié (32) et de la seconde moitié (33) est plus vers la tête de verrouillage que ne le sont les rainures de maintien (39a, 39b). Par conséquent, il est possible de fixer de nouveaux éléments de fixation à des sections d'élément de fixation manquantes à faible coût et en peu de temps sans envoyer la fermeture à glissière à un magasin de réparation, et également d'obtenir un aspect extérieur satisfaisant.
