An assembly for initiating a detonating explosive charge, e.g., a surface seismic charge, by low-energy detonating cord (LEDC) has a cord-connector fitted around a percussion-actuated detonator or booster, and a means of piercing a frangible package to enable the assembly to be embedded in the charge. In a preferred assembly, the connector is a plastic tube which fits over the actuation end of a booster shell whose opposite end is notched or serrated. A detonator preferably is fitted in a plastic cord-connecting tube whose end surface is tapered, or which has a pointed extension member, forming a spike. LEDC does not pose the fire hazard encountered with heavier cords in surface seismic operations in wooded or grassy areas.

A cord/initiator connector comprising a plastic tube having, at one end thereof, a transverse slot communicating with its bore and adapted to engage a length of LEDC, and its opposite end surface being tapered to form a package-piercing spike of sufficient length to protrude beyond the end of an initiator shell which said tube is adapted to hold, said tube being provided with retaining means adjacent said transverse slot for preventing the disengagement of a length of LEDC therefrom.
