Claim:
Device detachably connecting a wiper blade ( 12 ), to clean windows, to a driven wiper arm ( 10 ) featuring a wiper blade holder ( 50 or 150 ) and the wiper blade that can be placed on a window ( 20 ) with an elongated, rubber elastic wiper strip ( 18 ), the wiper blade featuring a band-like, elongated elastic supporting element ( 16 ) that is curved in a longitudinal direction over band surfaces ( 15 , 17 ), on a lower, concave band surface ( 17 ), the wiper strip ( 18 ) is arranged parallel to a longitudinal axis and, on an outer, convex band surface, a connecting element ( 26 ) sits, the connecting element ( 26 ) featuring two parallel wall surfaces ( 36 ) generally parallel to a plane generally perpendicular to the band surface and extending in the longitudinal direction of the wiper blade, whereby a pivot pin ( 42 ) projects from each wall surface and whereby longitudinal axes of the pivot pins are aligned, characterized in that an adapter ( 66 or 166 ) is positioned on the pivot pins ( 42 ) of the connecting element ( 26 ) to move in a pendulum fashion, and said adapter features means to connect to the wiper blade holder ( 50 or 150 ) of the wiper arm ( 10 ), characterized in that the two wall surfaces ( 36 ) are formed by outside surfaces on a T-foot ( 28 ) of the connecting element ( 26 ), the connecting element ( 26 ) having a T-shaped cross-section, at least in sections, and a T-head ( 30 ) facing the supporting element ( 16 ) and connected to the supporting element ( 16 ), characterized in that the adapter ( 66 or 166 ) essentially has a U-shaped cross-section including U-legs ( 70 or 170 ) to grip over the T-foot ( 28 ) of the connecting element ( 26 ) laterally, and a U-base ( 72 ) to cover the T-foot ( 28 ) of the connecting element ( 26 ), in each of the U-legs ( 70 ), an open-edge, slot-like recess is arranged towards a free end, the slot-like recesses having slot ends forming rest receptacles ( 76 or 176 ) for the pivot pins ( 42 ), characterized in that the adapter ( 66 or 166 ) is provided with collar-like projections ( 80 ) surrounding the rest receptacles ( 76 or 176 ) on outer surfaces of the U-legs ( 70 or 170 ), and characterized in that the wiper blade holder ( 50 or 150 ) of the wiper arm ( 10 ) grips over the adapter on its U-legs with side cheeks so that it fits and that open-edge recesses ( 56 or 156 ) are arranged in the side cheeks ( 54 ) for the collar-like projections ( 80 ) of the adapter.
