A guard to prevent the inadvertent operation of an inflator for use with an inflatable article, the inflator having a piercing pin which is operated by a manually operated lever. The guard of the invention, which is used instead of the formerly used headed frangible pin which extended through the lever and the body of the inflator on both sides thereof, is of U-shape and is mounted on the body of the inflator so that the broad main part of the guard straddles the lever when the latter is in retracted position, and the legs of the guard tightly pinch the opposite sides of the inflator body between them. The guard is simple and economical to make, can be quickly applied to the inflator body, is reusable, and can readily be applied in the field, in contrast to the formerly employed frangible pin which required the use of special heading equipment in order fully to apply it to the inflator body.
