Abstract

Un collier de serrage utilisé pour assembler un tuyau comporte une bande de fixation et une boucle de retenue. Le procédé permet d'assembler le tuyau de manière sécurisée et commode par simple traction de la bande de fixation, au moyen d'une portion de fixation recourbée progressivement vers l'intérieur contre les sections d'insertion saillantes et ouvertes de la boucle de retenue, sans qu'il soit nécessaire d'exécuter des actions difficiles et compliquées consistant à insérer la bande de fixation dans un orifice de la boucle de retenue. Ainsi, il est possible de procéder à l'assemblage du tuyau de manière aisée et sécurisée, y compris dans des environnements hostiles. La bande de fixation vient tout d'abord au contact de la saillie de blocage tout en passant par la boucle de retenue, lorsqu'elle est fixée autour du tuyau, puis vient à nouveau au contact des pattes de fixation-assemblage; la bande de fixation peut alors être assemblée aisément et de manière stable par double bandage à la boucle de retenue sans qu'il soit nécessaire d'utiliser un outil.
