The invention is based on a connecting element (36) for the articulated connection of a wiper blade (14) to a wiper arm (12) of a window wiper (10), wherein the connecting element (36) has a hub (50), which is open towards a vehicle window (16), for a bearing pin (26) fastened to the wiper blade (14), and at least one elastically flexible spring tongue (46) in order to keep the bearing pin (26) in the open hub (50), and the connecting element (36) furthermore has at least one bearing surface (60) in order to support it on a hook-shaped end (28) of the wiper arm (12). It is proposed that the hub (50) is open over half of its circumference, and the spring tongue (46), which blocks the opening of the hub (50) by means of a latching cam (48), yields elastically in the direction of the bearing surface (60), wherein the distance between the bearing surface (60) for the hook-shaped end (28) and the spring tongue (46) is dimensioned in such a manner that, in the fitted state, the hook-shaped end (28) blocks the spring tongue (46) in the direction of the bearing surface (60).
