An electrically conductive corewire connected proximate its distal end directly to the heating fuse element at a first electrical connection joint, while a separate insulated electrically conductive wire is electrically connected directly to the heating fuse element at a second electrical connection joint. An inner insulation sleeve placed over a distal section of the corewire covers the first electrical connection joint and is disposed between the insulated electrically conductive wire and the electrically conductive corewire. An outer insulation sleeve is disposed over a distal section of an assembly including the insulated electrically conductive wire, the inner insulation sleeve and the electrically conductive corewire. The outer insulation sleeve covers the second electrical connection joint.Ulf A)C
