An elongated flexible heater strip is provided having a transmission line section and a heater section employing a high mu material to control temperature at the Curie temperature of the high mu material; the above elements and a return buss being confined in a conductive sheath having a plurality of transverse slots to render the strap flexible, so that it may be cinched about a member to be heated; a strip of conductive material, such as copper, extending at least along the transmission line section interiorly of said sheath to reduce the resistance thereof and increase the current carrying capacity of the strap.
