A self-closing hinge comprises a pair of hinge leaves pivotally interconnected by an offset hinge pin. One leaf has a flanged head projecting substantially radially with respect to a sleeve of the other hinge leaf, within which the hinge pin is mounted. The external surface of the sleeve serves as a cam surface against which a follower element carried on the head of the other leaf is biased. The cam follower comprises a tubular spring-steel member oriented parallel to the hinge pin and generates a force through the head of the other leaf along an axis distally offset relative to the axis of the hinge pin. During closing of the hinge the follower is brought into registration with a pocket formed in the sleeve to effect a rocking movement of the follower about one edge of the pocket to generate a self-closing moment.
