a restraining actuation member having a fixed inclined cam surface formed on a part of its inner circumferential surface with an inner diameter gradually decreasing toward the distal end side; A movable inclined cam surface having a small diameter is formed opposite to the cam surface, and a pressure is applied to the inner circumferential surface of the cam surface, the inner diameter of which is approximately equal to the outer diameter of the connecting tube, and which retains and restrains the outer diameter surface of the connecting tube. A restraining surface is formed, and a plurality of slot grooves are cut alternately from the proximal end side and the distal end side at appropriate angular intervals, thereby reducing the relative movement of the inclined cam surfaces as they slide against each other. An automatic coupling device for a connecting tube, characterized in that it comprises a retaining member that enables diameter reduction and restoration to the original state.
