Abstract: The pipe coupling member has a female pipe coupling body, and a cylindrical front and rear cover members fitted to the female pipe coupling body. The front cover member includes a communication assembly including a communication terminal, a communication cable extending rearward from the communication terminal inside the front cover member and further extending rearward from the rear end of the female pipe coupling body, and a connector terminal at the rear end of the communication cable. The rear cover member is configured to allow the connector terminal to be passed forward inside the rear cover member along a hose attached to the rear end of the female pipe coupling body when the rear cover member is displaced rearward in a state where the hose and the communication cable are allowed to pass inside the rear cover member.

Abstract: Disclosed is a female coupling member which includes a housing having a fluid passage extending therethrough, a valve member selectively opening and closing the fluid passage, and a valve open-closed state indicating member. The valve open-closed state indicating member has a valve open state indicating part and a valve closed state indicating part and is displaced in response to the displacement of the valve member. When a male coupling member is connected to the female coupling member, and when the valve member is in an open position, the valve open state indicating part is visible from the outside of the housing through a window of the housing, whereas, when the valve member is in a closed position, the valve closed state indicating part is visible from the outside of the housing through the window.
