A heating device for recovering a heat-recoverable plastics sleeve about a portion of a wire harness comprises a housing having a heating location when the portion of the harness and heat-recoverable sleeve are introduced, and a heating unit that is movable between a rearward position in which it surrounds the heating location. The heating unit comprises a pair of heating jaws (5, 5') that open as they move toward the heating location and then close as they arrive at it so that the portion of the harness to be heated is completely enclosed within the heating unit. The jaws open again when they recede from the heating location to allow the harness to be removed.

Why it's free to use
- Filed April 9, 1992 and granted August 21, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 9, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 9, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
