Abstract
A fusible insert having protuberances on at least one surface is disposed between a heat recoverable sleeve and the substrate over which the sleeve is recovered. The protuberances provide for mechanical engagement between the liner and the sleeve or substrate. When the protuberance has substantially the same melting temperature as the liner and the sleeve has been recovered but insufficient heat added to make the insert flowable, the protuberances form detectable bumps on the outer surface of the sleeve indicating that more heat should be added to render the insert flowable.
