First Claim:

I claim:
1. In a spectacle frame comprising a face-piece and two legs, a hinge for connecting the face-piece to a respective leg, wherein the hinge comprises:
- a first hinge member connected to the leg and having two parallel spaced-apart plates between which a pin defining the hinge axis is mounted, and
- a second hinge member joined to the face-piece of the frame and having a hook which receives the pin within its aperture,
- and wherein:
- the first hinge member also includes an elongate blade which is flexurally resiliently deformable, the blade extending between the two plates in a plane perpendicular thereto and having one end jointed to the first hinge member and its opposite end facing the pin of the hinge,
- the hook of the second member has an outer surface which cooperates with the blade and includes a first cam portion for cooperating with the blade during folding of the leg against the face-piece so as to bias the leg into the folded position when the leg rotates about the hinge beyond the maximum point of curvature of the cam profile and to bias the pin into engagement with the hook to hold the pin and hook in assembled relation.
