The invention relates to safety priming device for an explosive charge, notably a shaped charge, comprising a pyrotechnic igniter and at least one igniting relay placed between the igniter and an explosive load. This priming device is characterized in that the igniting relay comprises means enabling the detonation wave produced by the igniter or igniters to be re-centered along the charge axis, said means comprising a confinement block having a bore converging between an external face positioned beside the igniter or igniters and an inner face positioned beside the explosive load, said bore filled with a relay explosive, the confinement block comprising means to prevent the propagation of a shock wave axially through the confinement block between the igniter or igniters and the explosive load.
