A pack for smoking articles having; a container; an inner wrap, which encloses a group of smoking articles and is housed in the container; a hinged lid, movable between a closed position and an open position, a collar, which embraces the inner wrap and is glued on the inside of the container so as to partially project out of the open top end and engage a corresponding inner surface of the lid, when the lid is arranged in a closed position; a slider, which is firmly connected to the lid and is coupled to the container in a sliding manner so as to slide relative to the container along a sliding direction; a locking system, which is interposed between the container and the slider and, in the closed position of the lid, prevents the slider from sliding relative to the container. The hindering of the sliding of the slider relative to the container, determined by the locking system, can be deactivated by an external action by the user to elastically deform at least part of at least one wall of the container.
