Abstract

The invention relates to a wiper blade (10) consisting of a rubber profiled element (48) comprising a wiper lip (50) and at least one carrier element (46) that can be connected to a wiper arm (18) by means of a fixing element (14) and a connection element (22). The fixing element (14) comprises a covering cap (16) and the connection element (22) fixed to the wiper arm (18) secures the wiper blade (10) perpendicularly to a pivoting axis (20) by means of a clip (52), on the end (54) thereof at an angle to the wiper blade. According to the invention, the covering cap (16) comprises an opening (34) or recess for the angular end (54) of the clip (52), on the side of the cap opposing the rubber profiled element (48), in the region of the connection element (22), said opening only partially overlapping the covering cap (16) in the mounted position.
