An attack repellant device to be worn externally by a user houses a replaccable container of repellent fluid (malodorous or irritating) which is selectively releasable to repel, discourage or subsequently identify an attacker or assailant. The container includes a portion which is breakable to release the fluid through a nozzle (or through a screen) by a pair of manually actuatable pushbutton fluid release members which can be depressed to break the container portion only after four manually actuatable pushbutton resettable trigger members are first depressed. The fluid release members mechanically interlock with each other and each fluid release member also interlocks with one pair of trigger members. The nozzle includes an optionally usable manually operable valve to prevent or terminate fluid release even after all pushbutton members are actuated. The device includes an electric safety alarm system to warn the wearer if any one of the trigger members has been unintentionally actuated.
