This invention concerns a perfected mechanical safety device for firearms such as automatic shotguns equipped with a safety device in the under-barrel grip where the safety device includes at least one safety pin or rod (11) that is axially moveable between an active position of disabling use of the firearm and an inactive position of enabling use of the firearm and, in association with his safety pin, at least one spring-loaded selector element (13, 14) that defines the said active and inactive positions of the safety pin, alternately, characterized by a safety body turning around an axis intersecting the moving direction of the safety pin between a position of locking the safety pin, thus inhibiting its movement from the active to inactive position, and unlocking it to permit movement from the active to the inactive position, the said safety body being enabled by a specific control key.
