stretch towards the rear.
The connector is received by longitudinal sliding into the front end of the arm, and the connector comprises means for assuring its locking according to the longitudinal direction in relation to the arm. To this effect, the flanks of the connector are received via longitudinal sliding, each respectively in two holes defined by the internal sides opposite from the two lateral flanges of the front end of the arm and which are unblocked towards the front, and the connector is inserted longitudinally from the front to the rear between the lateral flanges.
The front end of the arm comprises an upper transversal back that joins the two flanges, the connector comprising an elastic tongue that reaches horizontally towards the rear when the front body to whichassure its blockage according to the longitudinal direction in relation to the arm, characterized by the connector comprises a holding rod that reaches vertically with play across from a hole formed opposite in the central articulation part of the mounting element.
According to other characteristics of the invention:
the free lower end of the holding rod comprises a holding beak in order to keep the connector vertical, with play, in relation to the mounting element;
the holding rod is received longitudinally with play in the hole formed in a vertical slit with a longitudinal orientation;
the front end of the arm comprises an upper transversal back, the connector comprises an elastic tongue that reaches horizontally towards the rear while the front body to which it is linked via it front end forming
