Mild detonating cord confinement, particularly of the type including a metal covered mild detonating fuse as an inner core. The invention is directed to reducing cord diameter and weight, while totally confining explosive effects. The reduction in weight and diameter is achieved by employing a plurality of different coverings for the mild detonating fuse inner core, notably an extruded plastic jacket, a plurality of plastic fiber overbraid coverings and a stainless steel overbraid encircling the plastic fiber as an overbraid. A foamed polyethylene may be employed as the extruded plastic jacket.
