It is proposed that at least two support elements in the form of spring bars () having a round cross-section are provided in corresponding separate longitudinal channels (), between which the retaining rails () are arranged.

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

The invention relates to a device () for the jointed connection of a wiper blade (), having a wiper arm (), wherein a connector () intended to be connected to the wiper blade () has a joint part () which forms a joint with a joint part () on a connector () intended to be connected to the wiper arm, and one of the joint parts () is a hub () open in the longitudinal direction of the associated component (or), the hub being supported with respect to the other component () in the direction opposite () the hub opening () when in the installed state, wherein the side walls () of the connector () and of the connector () overlap. It is suggested that the side walls () of one component () has recesses () which are open to the wiper strip (), and plunge into the projections () in the wiper blade () operating position, such that both components () are locked against each other in the longitudinal direction.
