[origin: FR2754320A1] 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.
