Open the CIPO recordAbstract From the Canadian patent
An article comprising a heat-recoverable conduit is provided with a plug or cap within or around said conduit to prevent the ingress of contaminants. The plug or cap comprises two principal parts; the first part which is, hollow, sits inside or around the conduit and the second part, which is attached to or in engagement with the first part, blocks the conduit. The second part can be detached or disengaged before recovery so that, for example a supply, line can be passed through the conduit and the first art can then be removed, destroyed or deformed prior to or during recovery. The plug or cap may also act to prevent premature recovery of the conduit.
