The fitting 26 comprises a ball bearing 38 with a bore 40 whose diameter is substantially equal to the inside diameter of the sleeves 34, 34 '. The hinge pin 28 comprises a hollow cylindrical body whose outer diameter is substantially equal to the inner diameter of the sleeves 34, 34 'and 20 of the diameter of the bore 40 of the ball bearing 38. To avoid the exit of the hinge axis 28 of the sleeves and disassembly of the fastener, the assembly comprises a locking device for immobilizing the hinge axis in translation in the longitudinal direction. According to a first embodiment illustrated in FIG. 2, the locking device comprises - a screw 42 with a rod 44 housed in the hinge axis 28, a head 46 at a first end of the rod and a threaded portion 48 at a second end of the rod, - a self-locking nut 50 which is screwed on the threaded portion 48 of the screw 42, - a first washer 52, interposed between the head 46 of the screw and the hinge pin 28, whose outer diameter is greater than the outer diameter of the hinge pin, - a second washer 54 interposed between the nut 50 and the hinge pin 28 whose outer diameter is greater than the outer diameter of the hinge axis, - a pin 56 which passes through the nut 50 and the rod 44 of the screw so as to immobilize the nut 50 relative to the screw 42.
    [0004] According to this embodiment, the self-braking nut 50 corresponds to a first anti-rotation system and the pin 56 corresponds to a second antirotatio n system. During assembly, the screw 42 is introduced from a first end of the hinge axis 28 while the nut 50 and the pin 56 are operated from a second end of the hinge axis. Therefore, this first embodiment requires clearance zones on each side of the yoke 24. To overcome this disadvantage and allow an assembly of one side of the yoke, a second embodiment illustrated in FIG. been developed. This embodiment is more particularly adapted for the fasteners 18 20 located at the front of the engine 10. The elements common with the first embodiment are referenced in the same way. According to this second embodiment, the sleeve 34 of the first branch 30 of the yoke 24 comprises at one end an outer shoulder 36 projecting outwardly of the sleeve which bears against the inner face 301 of the first branch 30. and at a second end an inner shoulder 58 projecting towards the inside of the sleeve providing the stop function against which a first end of the hinge pin 28 bears to limit its translational movements in the longitudinal direction according to a first direction referenced by the arrow 60 in Figure 3. The sleeve 34 'of the second leg 30' of the yoke 24 comprises at a first end an outer shoulder 36 'projecting outwardly of the sleeve which bears against the face 301 'of the second limb 30' and at a second end an extension 62 which extends beyond the outer face 30E 'of the second limb 30 'and which comprises a threaded bore 64 whose diameter is greater than the inside diameter of the sleeve 34'.
