Abstract

This invention relates to a connecting member for a wiper blade and a wiper arm including a plastic structural member and a metallic locking spring. The structural member has a bearing bore as a receiver for a pivot pin. The locking spring is retained at a first end portion and intersects the bearing bore and acts upon the pivot pin by means of its center area. A second end portion of the spring forms a release key positioned behind the bearing bore. The release key of the locking spring is covered by a wing which is intergrally formed as part of the wall of the structural member by means of a film hinge.
