The balls have housings (5, 6) threaded by a female screw thread. The link made of shape memorizing steel, is provided with a male thread (8) assuring a connection of the link with the balls. A space (8`) is provided between the two balls. An independent claim is also included for a spectacle frame comprising a face articulated with respect to two branches of a spectacle by a hinge.
