1. Wiper lever (10) with a wiper arm (12) and a wiper blade (14) linked to it to clean windows (15), which is provided with a band-like, elongated, elastic supporting element (22) that has opposite concave-curved and convex-curved band surfaces (26, 28) and that is curved in the longitudinal direction over its band surfaces (26, 28), which features a rubber elastic wiper strip (30) that can be applied to the window (15) on its concave-curved band surface (26), on whose convex-curved band surface (28) an articulated part (20) sits, on which an adapter (40) is positioned so that it can move in a pendulum fashion, which has walls (42) aligned in the longitudinal direction of the wiper blade and above the band surfaces of the supporting element with planes situated at a distance from one another, and moveable locking means (68, 72) are arranged on the adapter, which cooperate with counter-locking means (66) of the wiper arm, characterized in that the locking means are arranged on at least one of the walls (42) and are moveable essentially transverse to the surfaces of these walls, characterized in that the adapter (40) has a U-shaped cross-section at least in sections, whose U-legs (42) form the walls between which supporting walls (34) embodied on the articulated part (20) suitably dip, characterized in that the adapter (40) suitably grips over two longitudinal walls (34) of the articulated part (20), which are situated at a distance from one another, with its U-legs (42), that articulation means (50, 38) are arranged on the longitudinal walls and on the U-legs (42) and that the locking means (72) of the adapter (40) that is composed of an elastic material are located on an extension (70) of the U-legs of the adapter extending beyond the longitudinal walls (34), characterized in that the wiper arm (12) that is driven in a pendulum fashion about a pendulum axis accommodates the adapter (40) with a connecting piece (18) that is U-shaped in cross-section and that the extension (70) of the adapter extends towards the pendulum axis (16), and characterized in that the locking means (72) of the adapter (40) that are preferably moveable against a restoring force are located on the outer side of the extension (70) facing U-legs (52) of the connecting piece (18) that is provided with the counter-locking means (66) of the wiper arm (12).
