PROBLEM TO BE SOLVED: To provide a temporary connection pipe temporarily disposed between the main pipe outlet parts of existing various types of pipes for supplying liquid such as city water and gases such as propane and the inlet parts of indoor pipes to securely position the main pipe outlet parts and the inlet parts of the indoor pipes so as to facilitate the installation of meters after the operations, provide excellent workability, prevent the steal of water since the outlet parts of the pipes are not allowed to communicate directly with the inlet parts of the indoor pipes, easily perform inspections for water leakage and gas leakage and pressure tests by supplying test liquid and gas only to the indoor pipes, and provide excellent reliability and maintainability by securely discharging liquid and gas after completing the inspections, and also provide excellent resources-saving since the meters can be collected and repeatedly used after the installation. SOLUTION: This temporary connection pipe comprises pipe side opening parts at both ends for connecting the main pipe outlet parts to the inlet parts of the indoor pipes, pipe connection screw parts formed at the pipe side opening parts at both ends, and outside opening parts communicating with the pipe side opening parts at both ends and opening to the outside.
