The present invention relates to a connection device between a valve and a pipe equipped with a position indicator and a safety grab part, capable of preventing leakage of refrigerant by simply connecting valves and pipes without complicated operations such as welding or expanding of pipes, and preventing galvanic corrosion between valves and pipes. According to the present invention, the connection device is provided with a protective means to prevent galvanic corrosion within the connection device, a location marker to track the location of pipes, and a complementary fixing device for pipes. At the same time, by optimizing a nut material, installation of pipes is simplified and malfunctions before and after connection can be prevented. 본 발명은 배관의 용접, 확관 등 복잡한 조작 없이 간편하게 밸브와 배관을 연결하여 냉매의 누설을 방지하고, 밸브와 배관 사이의 갈바닉 부식을 방지할 수 있는 위치 표식자와 안전 그랩부가 구비된 밸브와 배관의 연결장치에 관한 것으로서, 본 발명에 의하면 연결장치 내에 갈바닉 부식을 방지하는 보호수단, 배관의 위치를 추적하는 위치 표식자 및 배관의 보완 고정장치를 구비함과 동시에 너트 재질를 최적화함으로서, 배관의 설치가 간편해지고 연결 전후의 오작동을 방지할 수 있도록 한다.
