Abstract
An electric heating element having an improved electrical termination. The heating element comprises a conventional tubular metal sheath with a heating coil embedded in granular refractory material which is contained within the sheath. Terminal pins are electrically connected to opposite ends of the heating coil and extend outwardly of opposite ends of the sheath. My improvement provides for easy and efficient connection of a power conductor to a terminal pin and includes a metal sleeve having interengagement with a respective sheath end to provide protection for the terminal connection.
