A pivot joint is provided for pivotally connecting a wiper arm (1) into an aperture (17) in the main yoke or lever (3) of a windscreen wiper blade. The aperture (17) in the main yoke or lever (3) has two parallel side walls (19, 21)defining opposite sides of the aperture (17) and having a pair of coaxial holes (27), one in each side wall (19, 21). The joint comprises a connector (5) having a pair of trunnions (31) pivotally insertable into the coaxial holes (27) and movable between a first spaced position in which they are located in the holes (27) and a second position in which they are moved towards each other so as to be free of the holes (27) for assembly and disassembly purposes. The connector (5) has means for attachment to a wiper arm (1). The arrangement is such that when the wiper arm (1) is attached to the connector (5), the trunnions (31) are locked in their first position so that disconnection of the connector (5) from aperture (17) is impossible. <MATH> |
