FIELD: initiating devices, in particular, extensible devices for explosive charges having a detonator igniter with lowering detonating cords at blasting. SUBSTANCE: the extensible member has a basic gripping device and a protective tube. The basic gripping device has a means for holding the supply wire, designed for placement of the detonator supply wire in it so that the signal from the detonating cord would be transmitted to it. If desired, the extensible member is provided with a detonator to the extensible member. The detonator holder has dimensions and configuration providing for holding of detonators of various length in the proper position, providing for initiation of the explosive charge device. Placing the protective tube on the extensible member, explosive charge devices with the detonator igniter of various types may be used with detonating cords of various types, and the extensible member, having a protective tube suitable for the selected detonating cord, may be inserted in the explosive charge device with a detonator igniter. EFFECT: enhanced reliability of detonator connection to the detonating cord, and enhanced serviceability of it. 8 cl, 13 dwg
