TITLE Non-Electric Blasting Assembly ABSTRACT OF THE DISCLOSURE A percussion-actuated instantaneous or delay detonator transmits a detonation from a first length of low-energy detonating cord (LEDC) transversely positioned adjacent the detonator's percussion-responsive end to a U-shaped segment of a second length of LEDC held with its apex against the base-charge end of the detonator and the arms of the U extending away from the detonator. A directional connector for connecting a U-shaped segment of detonating cord adjacent each end of the detonator has identifiable donor- and receiver cord-housing sections, e.g., the receiver-cord- housing section has the shape of the head, and the donor- cord-housing section the shape of the butt, of an arrow. A connector adapted to hold receiver LEDC and high- energy detonating cord (HEDC) segments is internally configured to receive nested U-shaped segments of LEDC and HEDC only when the LEDC is adjacent the base-charge end of the detonator.
