A hinge for cold rooms or glass shutters includes a stationary support structure and a shutter movable between an open position and a closed position. The hinge includes a hinge body with a working chamber; a pivot coupled with the hinge body to rotate between the open and the closed positions of the shutter; a cam element unitary with the pivot; a plunger element sliding in the working chamber and having a slider with an operative face interacting with the cam element; a counteracting elastic member acting on the plunger element to move it between a position proximal to the bottom wall of the working chamber and a position distal therefrom. The cam element includes an elongated appendix extending from the pivot to come in contact engagement with the operative face of the slider. The pivot is placed at one of the side walls of the working chamber.
