A pyrotechnical firing installation comprises a plurality of detonators ( 3, 4 ), each with an electric cable ( 5, 6 ) comprising at least two connection conductors, and a surface line to which is connected the cable of the detonator. The surface line is formed by sections. Every section comprises a terminal or end part ( 5 a, 6 a) of the electric cable ( 5, 6 ) coming from a detonator ( 3, 4 ) and an end connector ( 7, 8 ) to electrically connect this terminal part ( 5 a, 6 a) to the cable of the next detonator, at a point of the latter defining the origin of its terminal part. |
