Abstract
A rail forming part of a backing strip for a windshield wiper squeegee is formed from a blank comprising a flat metal strip of narrow width which is formed with an offset portion that extends transversely on a longitudinally axis of the strip so as to protrude on one side, a claw retention slot being edge-punched from the offset portion and a pair of rubber squeegee-retaining barb elements being formed opposite from the offset portion so as to retain the squeegee to the backing strip.
