Position the member 1 at the fixed position. At this time, the sleeve 2 clamps the tube body 3 from the outer periphery due to its own spring action, and does not move naturally even if the sleeve 2 is released. Therefore, the tube fitting fixing recess 4 of the member 1 is
It is fitted onto the tubular body 3 from its radial direction, the sleeve engagement groove 9 of the member 1 is fitted into the engagement ear portion 10 of the sleeve 2, and the member 1 is pushed. At this time, the engaging ears 10 are tightened inwardly toward each other by the sleeve engaging groove 9 or the sleeve body,
The member 1 is fixed to the sleeve 2, and the sleeve 2 firmly clamps the tube body 3 from the outer periphery.

When repositioning or removing the member 1, slide the member 1 or the sleeve 2 in the opposite direction to the insertion direction so that the engaging ear portion 10 of the sleeve 2 is removed from the engaging groove 9. Get out, member 1
has been removed, and the sleeve 2 is attached to the pipe body 3.
The sleeve 2 can be repositioned by sliding it along the tube and the member 1 can be secured as described above, or the sleeve 2 can be removed from the tube 3.

(Embodiment) Hereinafter, in FIGS. 1 to 9 for explaining embodiments of the present invention based on the drawings, 1 is a member such as a tray, 2 is a sleeve, and the member 1 is passed through the sleeve 2 to the pipe body 3. (or a round bar).

The member 1 is integrally molded from a synthetic resin material, and as shown in FIGS. 8 and 9, a tube fitting fixation recess 4 is formed at one end in a substantially U-shape when viewed from above. There is. As shown in FIGS. 3 and 4, the fixing recess 4 is provided with a flange 5 for locking the sleeve that protrudes inward at the upper end, and the sleeve fitting body 6 has a flange 5 on the center side and the lower end of the tube body 3. Two sleeve engagement grooves 9 having openings 7 and 8 are provided in the sleeve, and the engagement grooves 9 are narrowed at the opening 7 end on the center side of the tube body 3. The bottom of the sleeve engaging groove 9 is a cylindrical surface, and the outer wall of the opening 7 is an inclined surface 9A that is sandwiched upwardly from the lower opening 8.

The sleeve 2 is integrally molded from a synthetic resin material and has a substantially C-shaped ring provided with spring properties, and the sleeve 2 is parallel to the axis and protrudes outward at opposite ends thereof.
An engaging ear portion 10 is provided protruding over the entire length in correspondence with the sleeve engaging groove 9.
A handle 11 is provided protrudingly on the opposite side. The inner surface 2A of the sleeve 2 is made into a cylindrical surface having approximately the same diameter or a slightly smaller diameter than the tube 3, and when the sleeve 2 is fitted onto the tube 3, its springiness allows it to come into close contact with the outer peripheral surface of the tube 3. It is like that. Further, the engaging ear portion 1
0, the spacing between the proximal end portions 10A is made smaller than the diameter of the tube body 3 to the extent that it can be fitted onto the tube body 3 from the outside in the radial direction due to the springiness of the sleeve 2. , the proximal outer inclined surface 10B is an inclined surface corresponding to the inclined surface 9A of the member 1. Therefore, in the sleeve 2, the outer inclined surface 10B of the proximal end of the ear portion is aligned with the inclined surface 9 of the engagement groove of the member 1.
A is pressed from both outside sides, and as the fitting deepens, the ears 10 are drawn inwardly toward each other, and the sleeve 2 is tightened and fixed to the tube body 3.

Note that a draft angle for molding is provided on the body portion 6 of the member 1, the sleeve engaging groove 9, and the outer circumferential surface of the sleeve 2, but this draft angle is not limited to the inclined surfaces 9A,
At least the inclination direction is made to match that of 10B.
