Abstract

The invention is based on a wiper blade (10) comprising a wiper strip (12), in the lateral longitudinal grooves (20) of which two parallel spring rails (24) are inserted as a supporting element in the head strip (16), wherein a spoiler (30) and end caps (32, 48) are provided on the rails. The end caps (32, 48) each connect with a flow profile (34) to the spoiler (30) and extend at the front sides facing the ends of the wiper blade (10) toward a wiper lip (14) over the spring rails (24). It is proposed that at least one end cap (32, 48) comprises a closeable assembly opening (38) in the region overlapping the spring rails (24) and the head strip (16).
