A childproof lighter has a housing adapted to hold a supply of combustible fuel, a valve in the housing between the nozzle and the supply and actuatable to emit the fuel, and an igniter on the housing adjacent the valve. An actuating element is depressible longitudinally downward between an upper position and a lower position and is coupled to the valve and igniter for actuating same when depressed into the lower position. This actuating element is formed with a longitudinally downwardly projecting skirt itself formed with a longitudinally projecting and laterally elastically deflectable tongue in turn formed with a laterally projecting catch formation forming a longitudinally downwardly directed stop surface displaceable on elastic deformation of the tongue between an outer position and an inner position. The housing is formed with a longitudinally upwardly directed stop surface longitudinally aligned with the finger stop surface in the outer position of the finger and upper position of the element and out of longitudinal alignment with the finger stop surface in the inner position of the finger. Interengaging holding formations on the tongue and on the housing releasably retain the tongue in the inner position when the tongue is moved downward out of the upper position and the tongue is sufficiently elastic to resume its outer position when moved from the lower position into the upper position and when the holding formations are out of engagement with each other.
