- the cover 1 is held on the stator 30 by means of a retaining means 4, cooperating with a retaining interface 14 (illustrated in FIG. 3) arranged on the cover 1.
- the cooperation between the retaining means 4 and the retaining interface 14 makes it possible to block the cover 1 in translation relative to the stator 30 in a direction parallel to the axis of rotation X, to prevent said cover 1 from moving away from the stator 30 and from the barrel 31, while allowing a rotation of said cover 1 around this axis of rotation X.
- the holding means 4 is fixed to the stator 30.
- the cover is advantageously blocked in translation by the blocking wall and cannot be removed by pulling on it to move it away from the stator.
- the key is therefore not accessible.
- the cover can be rotated around the axis of rotation so as to cause the key inserted in the cylinder to pivot. The key is therefore secure and cannot be removed. Blocking is achieved in a simple manner, by abutting the shoulder against the blocking wall.
- the cover 1 has inside an interior space 12 in which the gripping part 20, illustrated in dotted lines, of the key 2 is inserted.
- This space 12 opens onto an insertion face 13 of the cover 1 through which the gripping part 20 enters this space 12.
- the cover 1 further comprises means for locking the gripping part 20 of the key 2 in rotation around of the axis of rotation X so that the rotation of the cover 1 along this axis X rotates the key 2 inserted in the cylinder 31.

- the ring 42 protrudes from the stator 30 in a direction parallel to the axis of rotation X, in front of the front face of said stator 30. That is to say that it protrudes in front of the front face of the stator 30.
- the holding means 4 comprises a blocking wall 40 at the end of the ring 42 located in front of the front face of the stator 30, and which has a circular opening 41 facing said front face.
- the blocking wall 40 is substantially perpendicular to the axis of rotation X, distant from the front face of the stator 30, and the circular opening 41 is centered on this axis of rotation X. The diameter of this circular opening 41 is slightly greater.
- the section of the body 11 fits into a circle with a diameter slightly less than the diameter of the circular opening 41.
- the diameter of the cover 1 at the level of the shoulder 14 is greater than the diameter of the opening 41, but is less than the diameter. of the part of the ring 42 which protrudes in front of the front face of the stator 30.
- the cover 1 is held relative to the stator 30 in a direction parallel to the axis of rotation X by the cooperation between the locking wall 40 of the holding means 4 and the shoulder 14 of the body 1, but the body 1 can pivot about the axis of rotation X.
- the distance between the blocking wall 40 and the front face of the stator is chosen to be slightly greater than the thickness of the shoulder, i.e. the dimension of the shoulder para All together with the axis of rotation X, so as to limit the friction of the shoulder 14 against the locking wall 40 and of the front face of the stator 30 against the insertion face 13 of the cover 1 during the rotation of the said cover 1.
- the rotation around the X axis of the cover 1 enables the key 2 to be pivoted, and therefore the barrel 31 to be pivoted relative to the stator 30 between a first position and a second position.
- the first position corresponds to a stop position of the vehicle, in which the vehicle is switched off so that no electrical equipment can be activated
- the second position corresponds to a position where the vehicle is switched on. in which electrical equipment can be activated.
- the second position corresponds to a position where the electric motor of said vehicle can be activated to move the vehicle forward.
- the key 2 and the cylinder 31 can pivot into a third position corresponding to an actuation position of a starter launching the thermal engine.
- the body 11 of the cover 1 is cylindrical in general circular section with two flats, the two flats extending in the length of the body 11.
- the two flats are located on either side of the axis of rotation X. They allow a better grip of the cover 1 to make it pivot about the axis of rotation X.
- One of the flats may include inscriptions, for example indicating the maneuver carried out to start the vehicle, or other inscriptions.
- one of the flats may include a recessed area.
- the stator 30 comprises on its lateral surface hooks 32, for example 2, projecting from the lateral surface 34 of the stator 30, corresponding to the cylindrical surface of the stator, the profile of which in a direction parallel to the axis of rotation X forms a slope moving away from said stator 30 in a direction opposite to the front face, and forming at its end a step with the lateral surface 34.
- the ring 42 has fixing openings 43 facing these hooks 32.
- the ring 42 is threaded around the stator 30 by translation in a direction parallel to the axis of rotation X from the front face of said stator 30, until the fastening openings 43 of the ring 42 face each other. screws of the hooks 32.
- the shape of the profile of the hooks 32 allows a separation of the wall of the ring 42 during its threading, by sliding on the slope, until the hooks 32 enter the fixing openings 42, blocking then the extraction of the ring 32 in a motion ment inversely thanks to the interaction between these hooks 32, and more particularly the step created by these hooks, and the edges of the fastening openings 42.
- the stator 30 is cylindrical in shape with a circular section.
