A trigger lock for fuel pump nozzles at service stations comprises a relatively thin, flat piece of plastic, wood, metal, rubber or other material formed to have four pairs of opposing side edge regions. Opposite side edge regions are spaced apart different distances for different pairs so that the lock can be used to hold the nozzle triggers of different types of nozzles in a "full-on" pumping position, different pairs of side edge regions being used for nozzles having different trigger strokes. Preferably the spacings are 21/4, 21/2, 23/4 and 3 inches to enable use with most nozzles used by independent fuel distributors, by major distributors and for pumping No. 2 diesel fuel. In a variation, the trigger lock is incorporated into a vehicle fuel cap, the lock functioning as the portion by which the cap is gripped to remove and install the cap. In another variation, the intersecting corners of the side edge regions are rounded and the curved side edge is fluted or "coined" to provide a non-slip surface enabling the lock to stay in locking relationship with a nozzle trigger.
