Tear gas spray can effectively ward off a robbery attack. However, in many cases, the great speed and the surprise employed by expert attackers allow too little time for mobilization and aiming of the canister. The present invention fits over the canister, dispensing with the cap, and supplies a guiding tunnel over the discharge button for the distal phalanx of the triggering digit. Various identifying configurations of the parts are furnished and utilized so that, by feel alone, the fitted canister, resting in the pocket or purse, may be quickly grasped, rotated, and positioned in the hand, and the triggering digit tip may be placed in the tunnel, so that the fitted canister may then be quickly brought out and used, the pointing of the digital phalanx at the assailant's face assuring that the jet reaches its mark as the discharge button is depressed.
