Improved hinge, essentially characterized in that each hinged element, in number of two, which together form the general hinged body, are cylindrical, turned at the upper and lower ends, with straight planes in the central part and in tongue-and-groove arrangement by the arrangement of a stem that carries the lower part, which is housed in a matching recess in the upper part and which facilitates turning in both directions, creating an effective antifriction support.
