A backing (3) for a windscreen wiper blade has a groove (5) for receiving a blade element or insert and comprises mounting means in the form of pairs of flanges (19, 21) which permit the backing (3) to be held by a blade frame. The mounting means has a first pair of flanges (19) over which claws from a blade frame can be received. Spaced from the first pair of flanges (19) is a second pair of flanges (21) over which claws from a smaller width blade frame can be received. The first pair of flanges (19) is spaced near the bottom of the groove (5) and the second pair of flanges (21) is spaced below the first pair of flanges (19). This permits a blade element received in the groove (5) to be held by the backing for two different size width blade frames. |
