Open the CIPO recordAbstract From the Canadian patent
An apparatus which is suitable for sealing the end of an elongate electrical heater comprising both an insulating polymeric jacket and a metallic grounding braid surrounding the insulating jacket. Gripping members within the apparatus serve to grip both the insulating jacket and the braid, thus preventing slippage of one past the other. The apparatus is designed so that under some conditions the braid is readily pushed back from the end of the heater upon insertion.

Why it's free to use
- Filed December 7, 1989 and granted March 16, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 7, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 7, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
