Abstract

L'invention concerne la structure d'un connecteur pour tube à fluide, empêchant le grippage se produisant lorsque deux pièces de métal sont assemblées, et facilitant ainsi la connexion des pièces indépendamment du changement de dimensions dû à l'expansion et la contraction à cause de la température. La structure (1) du connecteur comporte un embout en métal (10) attaché à une extrémité d'un tube à fluide, inséré et connecté à une cavité (30) ainsi qu'une section renforcée en métal (40) permettant de supporter l'embout en métal (10) lorsqu'il est inséré. Une gaine en résine (43) comportant une fente axiale est interposée entre l'embout en métal (10) et la section renforcée en métal (40).
