A windscreen wiper support head has a pair of side walls 2 defining inturned arms terminating in upturned bearing walls 4 located towards the centre between the side walls. The bearing walls 4 each incorporate a notch 5 at their outer faces into which can be located a pin 6. The hooked end 7 of a spring 8 can then be located over the pin. The pressure of the spring holds the pin in place in the notch 5, enabling the pin also to act as a location anchorage for the hooked end 7 of the spring. <IMAGE>
