1. A device (16) connecting components of a wiper system for windows of motor vehicles including a wiper blade (10), a wiper arm (20), a wiperstip (24), and a band-shape delongated spring elastic support element (12), the device comprising a coupling part (21) arranged on an arm side, a coupling element (18) at a wiper blade side and pivotably connected to the coupling part (21), which coupling element is disposed in a center portion of the band-shaped-elongated, spring-elastic support element (12), on an upper band face (14) thereof remote from the window, and the wiper strip (24) oriented parallel to a longitudinal axis of the support element is located on a lower band face (22) of the support element, oriented toward the window, and can be pressed against the window, wherein from each long side of
the wiper blade (10), one pivot pin (41) disposed on the coupling element (18) protrudes, and a common longitudinal pivot axis (42) of these pivot pins extends transversely to the longitudinal direction of the wiper blade in a plane spaced apart from the
window, and each of the pivot pins (41), forming pivot means toward the blade, engages a bearing recess (44), associated to these pivot pins and forming the pivot means toward the blade, engages a bearing recess (44), associated to these pivot pins and forming the pivot means on the wiper arm side, of the coupling part (21), characterized in that the wiper blade (10), on the side of the upper band face (14) of the support element (12), is provided with a spoiler (26), extending on both sides of the coupling element (18) in the longitudinal direction of the wiper blade and having a leading-edge face (28), and that a leading-edge face (54, 154, or 254) extending longitudinally of the spoiler (26) is embodied at least on the coupling part (21), toward the wiper arm of the connection device (16).
