A wiper connector for a motor vehicle intended for the connection and articulation between a wiper arm and a component of a wiper blade is engaged longitudinally from rear to front inside the front end of the arm, which is curved longitudinally towards the rear in the form of a U. The wiper connector includes at least one elastically deformable element for securing the connector in the engaged position inside the front end of the arm and two longitudinal vertical flanks, which are designed to be received between two lateral wings of the blade component. The wiper connector is locked in the engaged position in the arm by a safety fastener mounted so as to be able to move between a closed position, in which it extends with regards to the securing element in order to prevent its elastic deformation, and an open position allowing the disengagement of the connector from the arm.
