(57) Hinge for a door or window frame, or a piece of furniture, comprising a hinging element
(12), of the male type, having a body (13) provided with a cavity (16), coaxial to
a hinging axis (X), into which a bushing (20) is suitable to be inserted, having its
own axial cavity (22) of a polygonal cross section and into which a pin (30) is adapted
to be inserted which has a first cylindrical part (31) and a second part (32) provided
with at least a zone (33) with a polygonal cross section, equal to that of the axial
cavity (22) of the bushing (20). The bushing (20) also comprises stop teeth (23),
adapted to cooperate with a circular throat (35) of the pin (30), which prevents the
latter becoming axially free.
