1. A heating cable connecting device that insulates a heating cable applied to a flexible heater to connect the heating cable to a terminal, the heating cable connecting device comprising:
an explosion-proofing device configured to be connected to one end of a connecting cable by explosion-proofing one end of the heating cable; and
an insulating device enclosing a connection between another end of the connecting cable and one end of a lead wire, the lead wire having another end connected to the terminal, thereby insulating and connecting the heating cable and the lead wire through the connecting cable;
wherein the explosion-proofing device includes a first sleeve, a first bobbin, and a first shield, the first sleeve including a first connection portion where the heating cable and the connecting cable are connected to each other, the first bobbin being disposed therein and spaced apart from the first sleeve, and the first shield surrounding an outer portion of the first bobbin,
wherein front ends and rear ends of each of the first bobbin and the first shield are closed by a first finishing part,
wherein the insulating device includes a second sleeve, a second bobbin, and a second shield, the second sleeve including a second connection portion where the connecting cable and the lead wire are connected to each other, the second bobbin being disposed therein and spaced apart from the second sleeve, and the second shield surrounding an outer portion of the second bobbin, and
wherein the insulating device is disposed at a position where the flexible heater and the terminal are connected.
