There are states of the workpiece against fire known, which, for example, of fire factory batteries of a plurality of combined with one another and associated facilities (10) are formed. The composition of the individual firework body and their ignition sequence are fixed during manufacture. However, it is in the case of the users of the fire against the need for a spacing of the workpiece, in many cases, even the composition and, if appropriate, also the ignition sequence of the pyrotechnic device (10) to determine. This is, in the case of fire, against the workpiece, certain conditions with in the manufacture of a fixed arrangement and ignition consequences of firework body (10) is not possible. The invention makes provision, fire against counts of the workpiece with a pyrotechnic device (10) or even more fireworks (10) with at least one coupling connection of a connection plug (14) and a connecting sleeve (15) to connect to one another. The in each case with a connecting sleeve (15), which connecting plug (14) at the same time serves for the production of a crossover firing between the last firework body (10) of a first fire work against state and a first firework body (10) of the workpiece to the first fire against state coupled next fire work against state. As a result, a plurality of by the user with the connector plug (36) and joining sleeve (37) of the workpiece, which is provided against fire states are coupled individually. This makes it possible to individually assembled, the formation of a firing fireworks.
