A safety device for automatically preventing a door accidentally closing completely. The door comprises at least one panel (2) provided with an actuator member (3) and hinged in a doorframe (4, 5, 6). The safety device comprises a moving member (10) displaceable between a safety position in which it prevents the door closing completely and a closure position in which the door can be closed, the moving member being connected (20) to the actuator member such that actuating the actuator member displaces the moving member towards its closure position.
