Abstract

L'invention concerne une fermeture à glissière (1, 80), dans laquelle une rangée d'éléments (12) comporte une section fragile (15, 86). Il est possible de détacher la rangée d'éléments (12) de la section fragile (15, 86) alors que les éléments sont en prise, et de séparer la première bande de fermeture et la deuxième bande de fermeture (10a, 10b). Des sections empêchant une sortie latérale (30, 71, 72, 73, 74, 84) sont disposées sur la deuxième bande de fermeture (10b). Les sections empêchant une sortie latérale (30, 71, 72, 73, 74, 84) ont une épaisseur supérieure à l'intervalle prévu pour l'insertion et le passage d'un ruban dans un curseur (50), pour empêcher une sortie latérale. Les sections empêchant une sortie latérale (30, 71, 72, 73, 74, 84) comportent au moins une section de petite largeur (32, 71b, 72b, 72d, 73b, 74b) dans une partie dont l'épaisseur est étudiée pour empêcher une sortie latérale. Ainsi, même quand la fermeture à glissière (1, 80) est soumise à une force de traction latérale, les sections empêchant une sortie latérale (30, 71, 72, 73, 74, 84) sont maintenues dans le curseur (50), et la fermeture peut rester fermée. Il est également possible, quand la rangée d'éléments (12) est détachée de la section fragile (15, 86), de retirer aisément du curseur (50) les sections empêchant une sortie latérale (30, 71, 72, 73, 74, 84), en les tirant.
