Abstract
A heat shrinkable sleeve or the like is heated by a ferromagnetic member which in turn is heated by a varying magnetic field, the ferromagnetic having a Curie temperature above the shrink temperature of the sleeve whereby when the sleeve is heated to its shrink temperature it tightly groups the members to be joined. Preferably a constant temperature is employed so that the ferromagnetic material will not rise above its Curie temperature.
