Abstract

La présente invention concerne un raccord amélioré à étanchéité en ogive ou similaires du type employé pour relier des tuyaux, souples ou rigides, à l'intérieur desquels circule un fluide, et en particulier elle se réfère à la partie de ces raccords à laquelle est relié un écrou 2 qui est vissé à une deuxième partie du raccord pour effectuer la liaison. Ce raccord comporte un élément tubulaire 1 se terminant en ogive sur lequel est enfilé un écrou 2; un élément annulaire 9, empêchant le dégagement de l'écrou 2 de l'élément 1, est ensuite enfilé sur ledit élément 1 et fixé à celui-ci de manière solidaire par soudage, par collage, ou par tout autre procédé similaire. L'écrou 2, qui est libre de tourner autour de son axe, est ainsi fixé à l'élément 1 sans qu'il soit nécessaire de déformer l'écrou lui-même pour obtenir cette fixation.
