Abstract
The invention relates to a cartridge having a projectile secured to a case that contains a propelling charge and closed by a base. A device for igniting the propelling charge has at least two energetic igniter cords that extend between an initiating means secured to a rear part of the case and the projectile. In this cartridge, the cords are joined at their rear part so as to form a strand, and they are fastened by at least one fastening means secured to the cartridge, the strand being connected to the initiating means by a packing gland making it possible to immobilize the cords both radially and axially relative to the initiating means while keeping the cords tight between their fastening means and the initiating means.
