ABSTRACT:
A connecting device has a first connector attached to a endoscope and a second connector communicating with a gas supply unit and adapted to be connected to the first connector. The first connector has a communication pipe having lower and upper ends communicating with the inside and outside of the endoscope, respectively. A valve plug is disposed in the pipe to be movable between the closing and opening positions. A rotating body is fitted to the outside of the upper end portion of the pipe to be rotatable between the first and second positions. The valve plug is moved in conjunction with the rotation of the rotating body. The second connector has an engaging slit adapted to engage a first retainer projecting from the pipe when the second connector is rotated after being fitted to the first connector. A second retainer projects inward from the second connector and is adapted to engage with an engaging portion of the rotating body when the second connector is fitted to the first connector. The second retainer rotates the rotating body to move the valve plug from the closing position to the opening position when the second connector is rotated from the fitting position.
