Abstract
A metal sheathed heater utilizes splice connections that connects ends of a heater cable with ends of a lead wire. Each splice connection has a connector that connects core wires of the lead wires and heater cable together. Heat shrinkable tubing surrounds the connector and ends of the heater cable and lead wires. An adhesive is interposed between the heat shrinkable tubing and heater cable and lead wire ends to bond with the heat shrinkable tubing and complete the splice connection. The metal sheath of the heater can be formed with an enlarged diameter portion to account for the heat shrinkable tubing surrounding the lead wire and heater cable ends.
