- the ankle is formed in a single piece of material.
- the invention also relates to a method of manufacturing a fixing device as defined above, comprising a step of manufacturing the ankle of permanently deforming a portion of the ankle by applying a deformation force on the ankle the deformed portion of the ankle constituting the locking portion of the ankle.
- the deformation force can be applied by crushing the deformation portion of the peg, for example by means of a clamping tool or a press or by means of one or more balls placed against an outer surface of the ankle in the portion to be deformed.

- the outer surface 20 of the first portion 18 of the pin 8 and the inner surface 16 of the housing 15 of the ring 7 and have complementary shapes. The complementarity of the shapes makes it possible to obtain a homogeneous contact of the outer surface 20 on the inner surface 16 during the insertion of the pin 8 into the housing 25, and consequently to obtain a homogeneous deformation of the second portion 12 of the the ring 7 (the second portion 12 of the ring 7 retains a cylindrical shape during the deformation).
- the first portion 19 also comprises a locking ring 34 projecting from the outer surface 20 and forming a shoulder 35 joining the outer surface 20 to the ring 34. The locking ring 34 is positioned at the junction of the first portion 18 with the second portion 1 9.

More specifically, the second portion 19 of the pin 8 has an outer surface 22 having a radial dimension smaller than an outer diameter of the first portion 18.
- the pin 8 also has a tapped bore 21 having a longitudinal axis X, the bore 21 being adapted to receive the screw 9 to fix the lug 6 on the ring 7 and hold the pin 8 in position in the ring 7.
- the bore 21 extends through the pin 8 in a longitudinal direction of the pin 8, over the entire length of the ankle. In particular, the bore 21 extends continuously through the first portion 18 and through the second portion 19 of the pin 8.
- the pin 8 has a wall 36 surrounding the bore 21, the wall 36 having, in the second portion 19, a thickness less than a thickness of the wall 36 in the first portion 18.
- This feature has the effect of favoring a deformation of the wall of the ankle in the second portion 19, while preserving the second portion 19 of a deformation during the insertion of the screw 9 into the bore 21.
- the ring 34 also stiffens the second portion 19 to preserve the second portion of a deformation.

- the internal thread 25 extends continuously in the first portion 1 8 and in the second portion 19 ankle 8.
- the second portion 1 9 of the pin 8 is distorted.
- the second portion 19 has a non-circular cross section because it has been deformed radially permanently. Therefore, in the second portion 19, the bore 21 also has a non-circular cross section.

- the internal thread 25 of the bore 21 has distortions (in this case the thread 25 has a non-circular helical shape), whereas in the first portion 18, the internal thread 25 of the bore 21 is not distorted (i.e. the thread 25 has a circular helical shape). Due to this distortion, the thread 25 is able to create in the zones 26, 27, 28 a frictional force on the external thread 26 of the screw 9 when the screw 9 is screwed into the pin 8.
- the radial deformation of the second portion 19 can be obtained by crushing the second portion 1 9, for example by means of a hydraulic clamping tool.

- the pin 8 is on the second side 4 of the wall 2.
- the tool 29 is actuated so as to cause the piston 31 to move inside the cylinder 30.
- the displacement of the piston 31 to the inside of the cylinder 30 has the effect that the piston 31 exerts on the pin 8 a tensile force in a direction parallel to the axis X tending to make the pin 8 penetrate further inside the ring 7 (c that is to say, approaching the first portion 1 1).
- the ring 7 is thus embedded in the orifice 5 of the wall 2 .
- the assembly tooling 29 is unscrewed from the ring 7 and pin 8 assembly.

During the screwing, the external thread 26 of the rod 24 of the screw 9 comes into engagement with the internal thread 25 of the bore 21 successively in the first portion 18 and in the second portion 19.
- the engagement of the external thread 26 in the internal thread 25 causes a radial elastic deformation of the second portion 19 (or locking portion).
- the second portion 19 of the pin 8 is deformed elastically under the action of the external thread 26 of the screw 9. This has the effect of creating a frictional force on the external thread 26 of the screw 9, which prevents further loosening of the screw 9 due to vibration of the wall 2 or a rotation of the lug 6 relative to the wall 2. The screw 9 is thus locked in the pin 8.
- the fixing device 1 which has just been described can be mounted on a support, without requiring access to both sides 3 and 4 of the support. This makes it possible, for example, to fix the lug 6 directly on a wall 2 of the carcass of an aircraft, without requiring the use of an additional specific support fixed to the wall 2.
