An improved connector for holding low energy detonating cord adjacent the percussion-actuation and surface of a detonator comprises a plastic tube having a detonator-receiving bore and one or more cord receiving transverse bores between a plastic end closure for the tube and the end of the bore of the tube. The transverse bore(s) form channels which permit the cord segments therein to span the actuation end surface of the detonator and result in improved reliability of initiation of the detonator.

A connector for holding at least one segment of a length of low-energy detonating cord (LEDC) adjacent a percussion-actuation end surface of a detonator, said connector comprising: (a) a plastic tube having a bore which is open at one end and closed at the opposite end by an integrally attached plas

A connector for holding at least one segment of a length of low-energy detonating cord (LEDC) adjacent a percussion-actuation end surface of a detonator, said connector comprising: (a) a plastic tube having a bore which is open at one end and closed at the opposite end by an integrally attached plastic closure layer, said tube having at least one open transverse bore between said closure layer and the end of the bore of said tube nearest thereto, said transverse bore being aligned on an axis that lies in a plane that is perpendicular to the longitudinal axis of the bore of said tube, with the proviso that when the number of said open transverse bores is more than one, said bores are parallel to, and separated from, one another, said tube being adapted to grip a detonator shell at its percussion-actuation end and to hold the detonator\s actuation end surface adjacent the end of the bore of said tube nearest said closure layer, said detonator shell having a side wall which is circumferentially crimped at said percussion-actuation end; and (b) on the exterior of said tube, means for securing the tube in an explosive primer.
