FIELD: blasting operations.
SUBSTANCE: invention relates to blasting operations and can be used in the initiation and transmission lines of a detonation signal. Device comprises a cylindrical sleeve with a closed end with the ability to locate and fix the detonator, clamping elements for the initiation signal transmission lines surrounding the detonator working end. Clamping elements are in the form of grooves connected to the cylindrical channels to accommodate the initiation signal transmission lines arranged symmetrically on the outside of the sleeve and parallel to the detonator axis. Each channel is provided with a pressure roller mounted on a ring rigidly fixed to the cylindrical sleeve.
EFFECT: simplifies the design, reduces the size, increases the reliability of the initiation system.
