Of the type of lighters that have a gas tank (1) equipped with an exit valve (2) leading to a burner (6), where a push-button (15) simultaneously determines the opening of the valve (2) and the operation of a piezoelectric ignition generator (7), whose central characteristic is the incorporation of a track mechanism (16), operated by a second push-button (14) using the tension of a spring (20), so that said track mechanism can stop the functioning of the valve (2), in turn obstructing ignition, even though it acts on the push-button (15), which is necessary for the functioning of the lighter and simultaneously act on the push-buttons (14) and (15), thus producing ignition. The lighter has been designed to obstruct the manoeuvres necessary to produce ignition when in the hands of a child.
