EASY RELEASE JOINT FOR FLEXIBLE TUBE

摘要

PROBLEM TO BE SOLVED: To hold a sure sealing state relative to a flexible tube even in the case of applying a force pulling out from a joint to the flexible tube. SOLUTION: The tip part of the flexible tube 20 formed of a corrugated tube 21 is inserted inside the joint 1. An annular sealing material 5 is stored in storage part 7 in the internal circumference of the joint 1. The tip of the corrugated tube 21 is inserted in the internal circumference of the sealing material 5. The sealing material 5 is formed with projections 16, 27 in its inner circumference so that, when a force pulling out from the joint 1 is applied to the corrugated tube 21, the projections 16, 27 are axially locked to the corrugated tube 21 so as to move in the pull-out direction of the corrugated tube 21 in the storage part 7 along with the corrugated tube 21.
