The invention relates to a defense device with a storage unit (1) that is provided with a nozzle unit (3), a solid, gaseous and/or liquid active substance stored in a storage compartment (5), a propelling charge and an igniting charge for igniting said propelling charge, in order to propel the active substance by way of a propellant that is produced when the propelling charge is ignited and to expel it from the storage compartment (5) through the nozzle unit (3) into free space. The storage device is further provided with a closing element (19) in the nozzle inlet zone, which prevents the active substance from escaping from the storage compartment (5) in the unignited state, but releases the nozzle unit (3) directly after ignition in such a way that no fragments of the closing element (19) can escape from the nozzle unit (3). A piston (21) in the storage compartment (5) can be displaced by the emerging propellant from a rest position into a final position of the piston in which it expels the active substance (15). Said piston (21; 87) interacts with a pressure-relief means (27, 85) which effects a complete pressure reduction of the propellant once the active substance (15) has been substantially completely expelled into free space. At least two of such storage devices (1a, 1b) can be used together in a self-defense device (11). Said self-defense device (11) has a plane of symmetry (41) with respect to which the storage devices (1a, 1b) are disposed. A trigger device that is provided with a single actuation slide (43), a so-called trigger, initiates expulsion of the active substance of only one storage device (1a, 1b) at a time with a predetermined distribution configuration into free space. The actuation slide (43) lies in the plane of symmetry (41) so that the self-defense device (11) can be operated both by left- and by right-handed persons.
