Abstract: The invention concerns an elastic hinge for spectacle frame, comprising first and second hinge elements including respectively first and second charniers provided with perforations for receiving a pivot pin when the second charnier is engaged between two faces of the first charnier so as to cause the perforations to be superimposed along a common axial direction countering the compression of a spring housed in one of the hinge elements. The pivot pin comprises two heads and a body integral with both heads to be engaged in translation through the perforations of the charniers until both heads are received in the perforations of the two faces of the first charnier, the body forming relative to both heads a recess to be received in the perforation of the second charnier by offsetting the latter relative to the axial direction of the perforations of the first charnier countering the compression of the spring.
