Abstract From the Canadian patent
A device for safely connecting the fuse (12 14) of two firework devices (20, 22) is provided. The device has a tubular member or connector (10), having a , first and second end. The ends of the connector are each adaptable to receive a fuse. When the device is in operation two fuses (12, 14), each from a , separate firework are inserted into the connector (10). This ensures that the flame from one fuse will be effectively transferred to the next. The device may also contain a primer (16) such as gunpowder within the interior of the connector to further ensure transmission of a flame from one fuse to the next.

Why it's free to use
- Filed June 28, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 28, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 28, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
