Answer
The heating element of an electric heater is made of an alloy having high resistance and when the current flows through it, the heating element becomes too hot and glows red. The cord on the other hand is made of copper or aluminum having low resistance, so current easily flows through it producing minimal heat. Hence, it doesn't glow.
