Device for hingedly connecting a wiper blade for windshields in motor vehicles to a wiper arm

A device pivotally connecting an elongated wiper blade (12) for a motor vehicle window (10) to a wiper arm (14) which can be moved between reversal positions and having a free end section, wherein said free end section is provided with a pivot bolt (40) extending essentially in a movement direction for connecting the elongated wiper blade, said wiper blade having an elongated, elastic support member (22) having an underside oriented toward the window, wherein said underside has an elongated wiper strip (20) disposed on it, wherein said wiper strip is placeable against the window (10), wherein the support member (22) has a coupling element (46) disposed thereon, said coupling element is provided with a transverse bore (68) that is open toward a top of the bore, wherein an opening width of said bore constitutes a narrow point (72) that is narrower than a diameter of the bore, wherein edge regions of the narrow point can be elastically spread open to a size of the bore diameter, characterized in that the support member has at least one elongated, spring-elastic support strip for holding the wiper strip (20), whose top (37) remote from the window (10) has the coupling element (46) disposed on it, wherein said coupling element is made of an elastic plastic and is provided with the transverse bore (68), wherein the device is provided with locking means (98, 99) for securing an operating position between the transverse bore (68) and the pivot bolt (40), wherein the locking means have a stop shoulder (98), said stop shoulder disposed on the wiper arm (14) pointing away from the window (10), and wherein said stop shoulder is associated with an opposing shoulder (99) of the coupling element (46) oriented toward the window (10).
