A safety device is mounted on a top side of a casing of a lighter, and includes an ignition button and a safety switch arranged on the ignition button. The ignition button is movably received in an open chamber defined in the top side of the casing to be depressible for ignition. The ignition button has a top face in which a slot is defined. The safety switch has a bottom face on which a projection is formed. The projection is movably received in the slot to retain the safety switch on the ignition button. A spring is arranged between the projection and the ignition button to provide the safety switch with a biasing force. The safety switch must be moved aside to disengage from a stop formed on a wall above the open chamber of the casing before the ignition button is depressed to set a fire on a fire outlet opening.
