In a fully concealed hinge (1), a connecting device (2) joins a first and a second fastening member (1a;1b) designed to be recessed in a door or openable furniture part and in a respective jamb, respectively, allowing them to move relative to each other between an open position and a closed position. A first cam element (5) and a second cam element (6) are formed on an arm element (20) of the connecting device (2), are located at different positions along a pin (3) which forms part the first fastening member (1a) and about which the arm element (20) rotates, and extend around the pin (3). In the first fastening member (1a), a first and a second tappet (50,60), biased by respective first and second elastic means (51,61), interact, respectively, with a corresponding active portion (52,62) of the first cam element (5) and the second cam element (6) in a respective angular field of rotation of the arm element (20) which are at least partly not superposed. The first and second elastic means (51,61) are loaded when the angle of rotation increases in the first or second angular field of rotation, respectively, and are released when the angle of rotation decreases, thereby causing movement towards the closed position.
