An improved cartridge 24 is disclosed for use in an explosively operated industrial tool 10. The cartridge 24 includes a retaining plate 60 for assuring that, after firing the cartridge 24, the spent primer 32 cannot be inadvertently ejected into the interior of the tool 10, where it can subsequently adversely affect the performance of the tool 10. The retaining plate 60 is washer shaped having an upwardly turned beveled peripheral edge 64 that interferingly engages portions of a gas check member 36 that holds the primer 32. The retaining plate 60 has a hole 61 that allows access to the detonator cap 68 for firing yet will not permit passage therethrough of the detonator cap 68 itself.
