A hinge for metal door or window frames consists of two hinge bodies (2, 3), each with a first through hole (6, 7) and a flap (8, 9) for securing it to a mobile frame or fixed frame (10, 11), and a hinge pin (18) inserted coaxially in the first holes (6, 7) to allow the hinge bodies (2, 3) to turn relative to each other about a central axis (19) of the pin (18); at least one of the flaps (8, 9) having an interchangeable portion (23) in which there is at least a second through hole (12, 15) in which an element (14, 17) for securing the flap (8, 9) to the mobile frame or the fixed frame (10, 11) can pass. |
