Claims

[Scope of Claim for Utility Model Registration] At the inner peripheral part of the distal end surface, an inner sealing means is provided on a part of the outer peripheral surface by extending toward the distal end so that the connecting tube can be fitted into the outer peripheral surface and sealed internally. a joint body having an insertion tube portion and forming a connection flow path within the insertion tube portion; and a joint body concentrically and integrally coupled to the joint body,
a guard stopper member having a fixed inclined cam surface whose inner diameter gradually decreases toward the distal end on at least a part of the inner circumferential surface, and an introduction portion extending and protruding from the distal end; the guard stopper member being fitted into the guard stopper member; A movable inclined cam surface having a slightly smaller diameter corresponding to the fixed inclined cam surface is formed on the outer peripheral surface to face the fixed inclined cam surface, and a movable inclined cam surface is formed at least on the tip side beyond the introduction part of the guard stopper member. a distal end flange portion that is extended, and a pressurized restraining surface having an inner diameter approximately equal to the outer diameter of the connecting tube and restraining and restraining the outer diameter surface of the connecting tube is formed on the inner peripheral surface. , 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 diameter due to mutual sliding of the inclined cam surfaces and reducing the original diameter. 1. An automatic coupling device for a connecting tube, characterized in that it comprises a retaining member that enables restoration to the state of the connecting tube.
