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.

1. An apparatus for coupling an electric match to a quickmatch fuse having an inner core of a pyrotechnic device, comprising:a) a hinged structure comprising a cover portion and a clamping plate, said hinged structure being movable between an open position and a closed position;b) means for latching
1. An apparatus for coupling an electric match to a quickmatch fuse having an inner core of a pyrotechnic device, comprising:a) a hinged structure comprising a cover portion and a clamping plate, said hinged structure being movable between an open position and a closed position;b) means for latching said hinged structure in said closed position;c) a first channel disposed in said cover portion of said hinged structure and having openings at both proximal and distal ends thereof, said opening at said proximal end being adapted to receive said electric match inserted thereinto, and said electric match being retained in a predetermined position within said first channel after insertion;d) means for positioning said quickmatch fuse proximate said first channel and for retaining said quickmatch fuse when said hinged structure is in said closed position;e) means for piercing the exterior covering of said quickmatch fuse, thereby producing an opening to the inner core thereof; andf) a second channel, communicative with both said opening at said distal end of said first channel and with said opening to said inner core of said quickmatch;whereby, upon ignition of said electric match, a flame therefrom is directed to said opening to said inner core by at least said second channel, resulting in ignition of said inner core by said flame.2. The apparatus for coupling an electric match to a quickmatch fuse of a pyrotechnic device, as recited in claim 1, wherein said pyrotechnic device comprises a fireworks display shell.3. The apparatus for coupling an electric match to a quickmatch fuse of a pyrotechnic device, as recited in claim 1, wherein said coupling apparatus comprises a one-piece thermoplastic structure molded from a thermoplastic resin.4. The apparatus for coupling an electric match to a quickmatch fuse of a pyrotechnic device, as recited in claim 3, wherein said thermoplastic resin comprises one of the resins: polypropylene, and polyethylene.5. The apparatus for coupling an electric match to a quickmatch fuse of a pyrotechnic device, as recited in claim 1, wherein said hinged structure comprises at least one integral hinge disposed between said cover portion and said clamping plate.6. The apparatus for coupling an electric match to a quickmatch fuse of a pyrotechnic device, as recited in claim 1, wherein said means for piercing comprises at least one of the shapes: a cone, and a pyramid, disposed on said cover portion.7. The apparatus for coupling an electric match to a quickmatch fuse of a pyrotechnic device, as recited in claim 1, wherein said hinged structure is manually movable from said open position to said closed position and said latching means is operable manually.8. The apparatus for coupling an electric match to a quickmatch fuse of a pyrotechnic device, as recited in claim 7, wherein said apparatus for coupling retains said electric match and said quickmatch securely within said apparatus when said hinged portion is latched in said closed position.9. The apparatus for coupling an electric match to a quickmatch fuse of a pyrotechnic device, as recited in claim 1, wherein said means for latching comprises at least one locking latch.10. The apparatus for coupling an electric match to a quickmatch fuse of a pyrotechnic device, as recited in claim 1, wherein said first chamber comprises a locating surface to facilitate retaining said electric match at a predetermined position therein.11. The apparatus for coupling an electric match to a quickmatch fuse of a pyrotechnic device, as recited in claim 10, wherein said first channel functions as a protective chamber for said electric match retained at said predetermined position therein.12. The apparatus for coupling an electric match to a quickmatch fuse of a pyrotechnic device, as recited in claim 10, wherein said first channel further comprises a strain-relief structure for retaining an external lead wire attached to said electric match.13. The apparatus for coupling an electric match to a quickmatch fuse of a pyrotechnic device, as recited in claim 1, wherein said means for positioning and retaining said quickmatch fuse comprises at least one ridge adapted to grip said quickmatch when said hinged structure is latched in said closed position.14. A method for coupling an electric match to a quickmatch fuse having an inner core of a pyrotechnic device, the steps comprising:a) providing an apparatus for coupling said electric match to said quickmatch fuse, comprising:a hinged structure comprising a cover portion and a clamping plate, said hinged structure being movable between an open position and a closed position;means for latching said hinged structure in said second, closed position;a first channel disposed in said cover portion of said hinged structure and having openings at both proximal and distal ends thereof, said opening at said proximal end being adapted to receive said electric match inserted thereinto, said electric match being retained in a predetermined position within said first channel after insertion;means for positioning said quickmatch fuse proximate said first channel and for retaining said quickmatch fuse when said hinged structure is in said closed position;means for piercing an exterior covering of said quickmatch fuse and producing a opening to the inner core thereof; anda second channel, communicative with both said distal end of said first channel and with said opening in said exterior covering of said quickmatch;b) placing said quickmatch fuse of a pyrotechnic device into said hinged structure; andc) moving said hinged structure from said first, open position to said second, closed position and latching said hinged structure in said second, closed position.15. The method for coupling an electric match to a quickmatch fuse of a pyrotechnic device, as recited in claim 14, the steps further comprising:d) applying a predetermined electric current to leads of said electric match;whereby said electric match is ignited, flame from the ignition of said electric match is conveyed via said second channel to said inner core of said quickmatch fuse, and said pyrotechnic device is ignited thereby.16. The method for coupling an electric match to a quickmatch fuse of a pyrotechnic device, as recited in claim 14, the steps further comprising:d) if said apparatus for coupling has not previously had said electric match installed therein, prior to said placing step (b), with said hinged structure in said open position, inserting an electric match into said opening at said proximal end of said first channel.
