ABSTRACT:
A coupling device (10) for coupling a detonator cap (20) with an unfixtured detonating cord (80, FIG. 3 ) after removing a shipping plug (41, FIG. 2 ), features a sleeve member (12) having a longitudinal sleeve bore (18) extending therethrough for receiving a detonator cap (20) therein. The detonator cap (20) extends to the transition end (22) of the sleeve member (12) so that the detonating cord (80) does not enter the sleeve bore (18). A nut member (14) has an aperture (24) for receiving the cord (80) and is secured to the sleeve member (12) with its aperture (24) aligned with the bore (18). A ferrule (16) is seated on the sleeve member (12) and grips the detonating cord (80) when the nut member (14) is secured onto the sleeve member (12).
