PROBLEM TO BE SOLVED: To provide a coupling element with a pressed second element. SOLUTION: This coupling element A has the second element B pressed into the coupling element along a longitudinal axis X-X' and comprises two superposed coaxial rings, namely a locking ring 2 and a safety ring 4 for rotating around a main body 1 of the element A. The locking ring 2 is axially immobilized with respect to the main body 1 while the safety ring 4 is able to slide with respect to the locking ring 2 and with respect to the main body 1. The locking ring 2 has at least one locking slot 23 for accepting a radially projecting part 51 of the second element B pressed into the element A, a notch 23 B capable of locking the part 51 to the element A. Furthermore, the safety ring 4 has at least one safety slot 43 and its notch 43B is capable of locking the part 51 to the notch 23B in a circumference direction. COPYRIGHT: (C)2008,JPO&INPIT |
