A resilient hinge for a pair of spectacles comprises a first part fixed to the spectacle frame and a second part hinged on the first part. The second part is extended by a cylindrical tube on which is slidably mounted a cylindrical sleeve to which an arm is fixed. A transverse pin fixed in the sleeve passes through opposed slots in the tube to angularly fix the sleeve on the tube. A spring in the tube urges a yoke-shaped stud against said pin to bias said tube, relative to said sleeve, towards the free end of the arm. Angular positioning of the tube and sleeve can be provided by cooperating longitudinal ribs. |
