A hinge is provided with two elements pivotally connected together for relative rotational movement about a hinge axis. The hinge has a spring formed of bent wire. The spring is mounted on one of the elements and a mechanism causes it to apply a biassing force between the two elements over at least part of their relative rotational movement. The biassing force is transmitted via a finger on the spring. A spreader is arranged to fit over the finger for engagement with the other element. The spreader extends continuously over the finger and engages substantially the whole of the finger.
