ABSTRACT:
A windscreen-wiper blade includes a moulded plastics holder constituted by a main bow with a central portion for the attachment of an operating arm and at least two secondary bows formed in a single piece with the main bow, and a wiper blade carried by a longitudinal support which is inserted between pairs of lateral retaining claws on the main and secondary bows. The main bow has two transverse centering and stop projections at its ends for preventing the support with its wiper blade from coming out of the holder longitudinally.
