• an elongated, rubber elastic wiper strip which is pressable against a window to be wiped and is held substantially parallel to a longitudinal axis by said elongated, spring-elastic support element;
• a connection device for a driven wiper arm, said connection device being loadable toward the window and secured to a middle portion of said spring-elastic support element, at a side remote from the window, said connection device being formed as a component which is separate from said support element;
• and a welding connection which connects said connection device with said support element, said support element being band-shaped, said connection device having a base resting flatly on a side remote from the window of said band-shaped support element and is connected to said band-shaped supporting element by said a welding connection said connection device having also legs joined by the base, said base on its side remote from said legs being provided with protrusions which are spaced from one another crosswise to a longitudinal extent of said support element by a distance which is adapted to a width of said support element, said protrusions being formed as strips which extend longitudinally of said support element.
