A device is proposed which is used to detachably connect a wiper blade (12) to clean windows, particularly of motor vehicles, to a driven wiper arm (10) featuring a wiper blade holder (50 or 150), whereby the wiper blade (12) that can be placed on the window (20) with a long-stretched-out, rubber elastic wiper strip (18) features a band-like, long-stretched-out elastic supporting element (16) that is curved in the longitudinal direction over its band surfaces (15, 17) on whose lower, concave band surface (17) the wiper strip (18) is arranged parallel to the longitudinal axis. On the outer convex band surface (15) of the supporting element (16) sits a connecting element (26), which features two parallel wall surfaces (36) mat are aligned in a vertical plane on the band surface and extend in the longitudinal direction of the wiper blade and that a pivot pin (42) projects from each wall surface, whereby the longitudinal axes of the two pivot pins are aligned with one another. An especially simple embodiment of the articulated connection with an integrated connecting device is achieved if an adapter (66 or 166) that can move in a pendulum fashion is positioned on the two pivot pins of the connecting element (26), and said adapter features means to connect to the wiper blade holder (50 or 150) of the wiper arm (10).
