Abstract

The invention is based on a wiper blade (12) with an elongate, spring-elastic carrying element (36) which is precurved in a concave fashion with respect to a vehicle window (22) and has two spring rails (52, 66) which run parallel to one another in a plane, and having a wiper strip (24) which is held with a web (34) of its head strip (30) between the spring rails (52, 66) via the carrier element (36), said spring rails (52, 66) being inserted in longitudinal grooves (32) on both sides of the web (34), wherein the wiper strip (24) is secured in the longitudinal direction (20) relative to the carrier element (36) at least close to one of the ends of said wiper strip (24). It is proposed that the spring rails (52, 66) have, at the longitudinal sides facing one another in their end regions, clips (60, 74) with cutters (62, 76) which, in the mounted state, cut into adjoining walls of the longitudinal grooves (32).
