A gas lighting rod comprises a gas release valve and a piezoelectric igniting system, both operated by a spring-loaded operating member, and a spring-loaded safety member which has to be operated to release the operating member. The operating member is aligned transversely and the safety member includes a pivoted lever having a lock/release arm extending generally along an axis of the operating member and interacting therewith, and a control arm engaged on an other side of a pivot and from an opposite side of the lighting rod from the operating member. The lock/release arm is substantially enclosed within the operating member, and its end is sloped such that its engagement with the operating member tends to urge the end into a locked position if a user attempts to operate the operating member without first fully operating the safety member.
