EASY RELEASE COUPLING FOR FLEXIBLE TUBE

摘要

PROBLEM TO BE SOLVED: To insert a corrugated tube of a flexible tube inserted into an easy release coupling up to a prescribed position without fail. SOLUTION: A flexible tube 1 is connected with a cylindrical easy release coupling with one operation by inserting a tip part of the flexible tube 1 formed at a corrugated tube 2 into the easy release coupling from an opening at an end part of the coupling. At the inside of the easy release coupling 11, a means 41 for presenting a click action in cooperation with the corrugated tube 2 when the corrugated tube 2 is inserted up to a prescribed position is provided. By inserting the corrugated tube 2, a response that the corrugated tube 2 hits on the means 41 presenting the click action is provided. When inserting force is further imparted to the corrugated tube 2, receiving the response, the corrugated tube 2 is further inserted into the coupling by the inserting force and the response is released.
