ABSTRACT:
A backing strip of a wiper blade refill unit is provided with a narrower element engaging slot to reduce wiper element disengagement from the backing strip, with a greater width to reduce backing strip disengagement from the claws of the superstructure and with a retaining tab for positive engagement with a flat U-shaped end clip to eliminate accidental end clip separation from the backing strip.
