For a form-fitting securing of the passage element (20) on the combustion chamber wall (16), the passage element (20) and the combustion chamber wall (16) have at least in part a conical shape. On the side facing the pyrotechnic charge (12), the passage element (20) has a collar (38) which acts as a spacer between the passage element (20) and the pyrotechnic charge (12).
