  • the latter has a general square shape. It has two sections 82 for supporting the arch 22, extending parallel to one another and perpendicularly extending the curved ends 80 of the lever. These support sections 82 are extended by two parallel sections to each other, denoted 84, extending perpendicular to the sections 82.
  • the sections 84 constitute a lever-holding arm. They are connected one to the other by a loop 86 forming a tongue for gripping the lever.
  • the loop 86 is angularly offset by about 30 ° relative to the arm 84.
  • the loop 86 is connected to the ends of the sections 84 by two parallel sections 88 of reduced spacing adapted for engagement elastic on a retaining tab 89.
  • This retaining tab 89 extends perpendicularly to the free arm 42A towards the outside of the clevis. It has a pointed end and has a thinning in the vicinity of its connection zone with the arm 42, adapted to receive the two sections 88.
  • the tab 89 and the sections 88 allow a retention of the lever on the outer bracket by elastic engagement of this one on the retaining tab 89.
  • the arch 22 comprises, in its middle part, a connecting pad 90 constituted by a cylinder attached around the shaped metal strip constituting the arch 22.
  • the pad 90 has two flats angularly offset by approximately 30 °.
