A pack for smoking articles comprising: a group of smoking articles housed in an inner container; an outer container, housing on the inside and in a sliding manner, the inner container; and a locking system. The locking system comprises an abutment element integral with and arranged inside the outer container; a first wing integral with the inner container and movable relative thereto so as to be arranged in abutment against the abutment element when the inner container is in a closed position, thus preventing the inner container from sliding from the closed position to an open position; and a second wing obtained on and movable relative to the outer container so as to be pressed inwards and, hence, move the underlying first wing accordingly to release the first wing abutting against the abutment element and allow the inner container to slide from the closed position to the open position.
