ABSTRACT:
There is provided a molded polymeric coupling device incorporating integral hinges, latches and strain-relief features adapted to receive an electric match having a protective chamber, and a quickmatch fuse of a pyrotechnic device. After the quickmatch fuse is suitably placed in the coupling device, it is latched in a closed position around the quickmatch fuse. A piercing structure such as a cone forms an opening in the outer layer of the quickmatch fuse so that, upon ignition of the electric match, flame therefrom is directed into and ignites the central blackmatch core of the quickmatch fuse. The coupling device allows rapid and accurate attachment of an electric match to a quickmatch fuse at the fireworks display site by persons of limited skill and/or experience. The electric matches are protected by the coupling device, preventing unexpected ignition from impact, friction, ESD, or other similar ignition sources.
