The invention concerns a method for making captive a screw (1) comprising a head and a threaded body and several types of sleeve tubes (2) for implementing the method. The method consists in screwing at the end of the body of the screw opposite the screw head, a cylindrical sleeve tube (2) tapped in a way complementary to the threading of the screw (1) body, the sleeve tube being externally threaded, and immobilising the sleeve tube with respect to the screw. For implementing this method, the invention also provides externally threaded and internally tapped sleeve tubes and specially adapted by the addition of immobilising means on the screws.
L'invention se rapporte à un procédé pour rendre imperdable une vis (1) et à plusieurs exemples de manchon (2) pour mettre en oeuvre ce procédé. Selon l'invention, il est donc prévu un procédé pour rendre imperdable une vis (1) comportant une tête et un corps fileté. On vient visser à l'extrémité du corps de la vis opposée à la tête de la vis, un manchon (2) cylindrique taraudé de façon complémentaire au filetage du corps de la vis (1), manchon fileté extérieurement, et on vient immobiliser le manchon par rapport à la vis. Pour la mise en oeuvre de ce procédé, l'invention prévoit également des manchons filetés extérieurement et taraudés intérieurement spécialement adaptés par l'adjonction de moyens d'immobilisation sur les vis.
