Claims

[Claims for Utility Model Registration] 1. In a tube joint that is prevented from coming off by forming a deformed part on the tube when the tube is attached, the male threaded part 1 and the tube attachment part 2
a tube T made of fluororesin or the like that is fitted into the tube attachment portion 2;
, a ring 4 with a split groove that fits on the outer surface of the tube T, and a female threaded portion 5 that is threadedly engaged with the male threaded portion 1.
and an inner wall portion 6 that presses against the ring 4 to apply a compressive force to the tube T from its outer surface toward the center, and a tube T that is generated as the diameter of the tube T increases due to insertion into the tube attachment portion 2. and a cap nut 8 having an acute-angled sloped bottom part 7 which bends the slope part S of the tube fitting part 2 and presses it in a self-biting manner. 2. The tube joint according to claim 1, wherein a projection (or recess) 9 and a recess (or projection) 10 are provided on the outer peripheral surface of the tube attachment portion 2 and the inner peripheral surface of the ring 4, respectively, for preventing the tube from coming off.
