PROBLEM TO BE SOLVED: To provide a valve connector making it hard to leak a sealing agent at the time of release of pressure. SOLUTION: A pressure releasing valve 25 is attached to a hose side connection member 50. The operation part 25A of the pressure releasing valve 25 is inserted in an insertion hole 50F and one end part thereof is protruded to the outside from the insertion hole 50F while a push button 25C having a diameter larger than that of the insertion hole 50F is formed to the leading end part of the operation part 25A. A valve part 25B is provided to the other end part of the operation part 25A to be made larger than a pressure releasing hole 20A and arranged to the part of the pressure releasing hole 20A in a catch tank 20. A coil spring 24 energizes the pressure releasing valve 25 to a closing position Q1 where the pressure releasing hole 20A is closed by the valve part 25B. When the pressure releasing valve 25 is arranged at an open position Q2, a flow channel SR is allowed to communicate with a pressure releasing space PR and opened to the outside through an open hole 20B.
