Detonation device including coupling means

A coupling device (10) for coupling a detonator cap (22a, 22b) with a detonating cord (82) features a sleeve member (12) having a longitudinal lore (18) extending therethrough for receiving a detonator cap (22a, 22b) in one end and a detonating cord (82) in the other. The coupling device (10) includes a nut member (14) having a aperture for receiving the cord (82) and having a compression surface (34) for hearing against a compression portion defined below when the nut member (14) is secured onto the sleeve member (12). The nut member (14) may he secured to the sleeve member (12) with its aperture aligned with the bore (18). A compression portion (31) associated with the sleeve member (12) responds to pressure from gripping a cord (82) when the nut member (14) is secured onto the sleeve member (12). Thus, a cord can be securely disposed in detonation signal transmission relation to a cap without having special coupling hardware.
