A cooling water recovery line 11' extending from the liquefied gas tank 9' is arranged in parallel with the fuel supply line of the liquefied gas tank 7, and connected thereto with a thermally conductive clip 19 to form the second heating section 8. In a preheating vaporization device for an internal combustion engine, a thermally conductive clip 19 that connects a cooling water recovery line 11' and a fuel supply line 5 arranged in parallel is connected to the cooling water recovery line 11' and the fuel supply line 5, respectively. connecting pieces 20, 21
1. A preheating vaporization device for an internal combustion engine for liquefied gas, characterized in that clip elements 22, which are extended as a single unit, are connected by a connecting band 23.
