PROBLEM TO BE SOLVED: To conduct pressure proof test while a protection cap is installed on a pipe coupling. SOLUTION: A flow path 3 where fluid passes is formed. The test device comprises a pipe coupling A where a connector 1 for connecting a pipe C is formed at the end of the flow path 3, a protection cap B installed at the connector 2 of the pipe coupling A and covering the connector 2, a holder 20 where the first coupling 22 holding the pipe coupling A in which the protection cap B is fitted is formed, and an adaptor 30 fixed to the holder 20, where a coat 31 covering the protection cap B is formed. In the protection cap B, a water path hole 15 communicating with the flow path 3 of the pipe coupling A is punched and coupled with the coat 31 of the adaptor 30 while being held by the holder 20 so that pressure proof test can be conducted while being installed in the connector 2 of the pipe coupling A.
