Claim:
A hinge for supporting and maneuvering doors, consisting of two wing-shaped elements for fastening to a frame part and to a door part respectively, each of said wing-shaped elements including at least one appendix projecting therefrom, a hinge pin pivotally connecting said wing-shaped elements together for fastening to a frame part and to a door part, respectively, and for mutual hinging about a pivoting axis in a pivoting area, wherein at least one of said appendixes of a first one of said wings is shaped as a cylindrical body on the surface of which there are formed axial grooves, said grooves being disposed at a circumferential distance from each other, and in that with a second one of said wings, opposite to said at least one of said appendixes, there is at least one push element engagement with one of said grooves, at least partially elastically yielding for selective engagement with one of said grooves to prevent undesired hinge rotation, and wherein said at least one push element consists of a pair of ribs parallel to the pivoting axis of the hinge, said ribs being kept together by elastically yielding connecting elements.
