ABSTRACT:
A tube can be easily attached to and detached from the tube joint by one hand. The tube joint comprises: a body proper having one open end, from which the tube is inserted; and a locking member locking the tube in the body proper. The locking member includes: a ring section sliding on an inner face of the body proper and moving in an axial direction; a plurality of flexible extended sections extended from the ring section toward the one open end of the body proper; and a plurality of claw sections radially projected inward from front ends of the flexible extended sections. The body proper has a tapered section, which reduces a diameter of the front ends of the flexible extended sections when the locking member is moved toward the one open end and the front ends of the flexible extended sections enter the tapered section, whereby the claw sections bite and lock the tube.
