Bolt built into a connector of a wiper arm for an on-board washing line

A windshield wiper for automotive vehicle comprising:

• a windshield wiper blade articulated on a windshield wiper arm with an arm-blade connector, and a washer fluid projection device arranged on the windshield wiper blade and connected by a coupling device to a washer fluid supply channel extending at least in part along the windshield wiper arm;
• wherein the coupling device is integrated in the arm-blade connector for automatic coupling of the projection device with the supply channel during the connection of the windshield wiper blade to the windshield wiper arm and for automatic decoupling of the projection device from the supply channel during the disconnection of the windshield wiper blade from the windshield wiper arm;
• wherein the arm-blade connector comprises a connector first portion integral with the arm and a connector second portion integral with the blade;
• wherein the coupling device comprises a coupling first part integral with the arm and a coupling second part integral with the blade, wherein the coupling first part is integrated in the connector first portion and the coupling second part is integrated in the connector second portion, making the coupling device integral with the arm-blade connector;
• the connector first portion defining an opening and the connector second portion including a latch-lever suitable to be positioned in said opening to ensure the connection between the arm and the blade, wherein the latch-lever is used to lock the coupling first part and the coupling second part together;
• and wherein the latch-lever is pin-shaped and comprises an upper zone with an opening sized to allow for the passage of a head-shaped part of the first part of the coupling device and a lower zone with an opening sized to prevent the passage of the head-shaped part of the first part of the coupling device, said opening of said lower zone being smaller than the opening of the upper zone.
