A hot melt adhesive hose assembly comprises a heater circuit wrapped around an external surface portion of the hose assembly, a temperature sensor, and an elongated thermal fuse which is likewise wrapped around an external surface portion of the hose assembly such that successive spiral turns of the thermal fuse are effectively interposed between successive spiral turns of the heater circuit. The thermal fuse may be electrically connected in series with the heater circuit so as to effectively terminate electrical power to the heater circuit as a result of the melting of the thermal fuse, or alternatively, the thermal fuse may be electrically connected in series with the temperature sensor, so as to detect abnormal temperature levels at substantially any location throughout the length of the hose assembly.
