the front and that is formed opposite from an external lateral side of the mounting element;
the flanks of the connector are received between two lateral flanges of the front end of the arm, and the rear abutment is made up of a rear edge of a lateral flange;
the surface of the abutment oriented towards the front is a front edge that longitudinally marks a portion in relief of the external lateral face of the mounting element;
the portion in relief is vertically defined towards the top by an upper edge with a longitudinal orientation and inclined in order to make a guiding ramp of the front end of the arm during the mounting of the latter onto the connector;
the connector is inserted longitudinally from the front to the backbetween the lateral flanges of the front end of the wiper arm;
the flanks of the connector are spread transversally away from each other towards a mounting position in order to allow the articulated mounting of the connector on the central articulation part of the mounting element then are led towards an articulation position in which the articulation means of the connector cooperate with the complementary means of the mounting element, and the flanks of the mounting element of the blade are received between two lateral flanges of the end of the arm that prevent the flanks of the connector from spreading transversally from their articulation position towards their mounting position;
the flanks of the connector comprise two lugs notably cylindrical with a horizontal axis that reach away from each
