The cover lock/safety device (1) of a pressure cooker (2) substantially comprises a cover handle (10) hinged onto the cover (3), which handle his formed by a first, hook-shaped element (16), and a second element (17) extending from the extension of said first, hook-shaped element. The first element (16) gets engaged in (12) to the side surface of the cooker body (4), tightly closing the said cover (2). When the cooker operates, the inner pressure inside the cooker (2) pushes outwards a pin element (11) which, in said extended position, engages the free end of said second element (17). Thus, the handle (10) results to be locked when the cooker is under pressure. The device is hence easy to use and, simultaneously, safe.
