The connector block allows the transmission of the shock wave that travels along the donor tube (1) to several receiver tubes (4), setting between them a delay device (6) with its corresponding pyrotechnic delay formula (8), and an explosive charge (9), all these components being integrated within the body (4) of the connector block in such a way that the explosive charge (9) is parallel and adjacent to the receiver tubes (10), which are on a parallel plane to said explosive charge and are positioned at right angles to it, inside which a detonator is housed. The explosive charge (9) is positioned so that all the tubes (10) held in the slot (11) are initiated in similar conditions, without suffering the effects of structural differences, thus achieving a homogeneous and safe initiation that does not produce metal shrapnel that could damage the receiver tubes (10).
