The distances L1 and L2 are distances in a direction perpendicular to the base 19, and the distance L1 is larger than the distance L2.

Next, the process in which the insert clip 10 holds the tube 11 will be described. As shown in FIG. 2, the mounting portion 14 is engaged with the mating member 12, and the insert clip 10 is mounted on the mating member 12. The insert clip 10 is separated from the tubular body 11 and the end 18A is located between the end 17A and the base 19. Further, the end portion 17B and the end portion 18B are separated by a gap L3, and the engaging claw 26 and the engaging claw 28 are all released. When the insert clip 10 is viewed in a plan view as shown in FIG. 2, it is surrounded by the base portion 19, the protruding portions 15, 16, a part of the outer surface 17C of the first arm portion 17, and a part of the outer surface 18C of the second arm portion 18. The second space B1 is formed. Further, a first space B2 is formed between the inner side surface 17D of the first arm portion 17 and the inner side surface 18D of the second arm portion 18. As shown in FIG. 2, the distance between the protruding portion 15 and the protruding portion 16 is the widest in the state where no external force is applied to the insert clip 10.

The operator moves the tubular body 11 in the thickness direction, for example, the arrow A1 direction in a plane perpendicular to the center line P1, and allows the tubular body 11 to pass between the end portion 17B and the end portion 18B. , A part of the tube 11 is made to enter the first space B2. Here, when the distance L3 between the end portion 17B and the end portion 18B is smaller than the diameter φ1 of the tubular body 11, the operator can use the first arm portion 17 and the second arm portion 17 so that the distance L3 is larger than the diameter φ1. At least one element of the arm portion 18, the hinge portion 24, 27, and the protrusion portion 15, 16 is elastically deformed.

Then, after a part of the tubular body 11 enters the first space B2, the end portion 17A comes into contact with the outer surface 11A of the tubular body 11 as shown in FIG. The ends 17B and 18B both come into contact with the outer surface 11A of the tubular body 11. When the operator further pushes the tubular body 11 in the direction of the arrow A1, the first arm portion 17 operates counterclockwise with the hinge 24 as a fulcrum, and the end portion 17A is pressed against the end portion 18B. Then, the operating force of the first arm portion 17 is transmitted to the second arm portion 18, and the second arm portion 18 operates clockwise with the hinge 27 as a fulcrum. The ends 17A and 17B slide along the outer surface 11A of the tubular body 11.

Further, the end 18A gets over the end 17A and the end 18A is separated from the end 17A. The end 18A is in contact with the outer surface 11A of the tubular body 11 as shown in FIG. 4, and the end 18A and the end 18B slide along the outer surface 11A of the tubular body 11. Further, the contact portion 25 of the end portion 17A comes into contact with the outer surface 11A of the tubular body 11. Here, a part of the end portion 18B is located outside the end portion 17B in the diameter direction (thickness direction) of the tube body 11. In this way, all of the tubular body 11 in the radial direction enters the first space B2.

When the operator further pushes the tubular body 11 in the direction of the arrow A1, the first arm portion 17 operates further counterclockwise with the hinge 24 as a fulcrum, and the end portion 17A approaches the first component portion 20. Further, the second arm portion 18 further operates clockwise with the hinge 27 as a fulcrum, and the end portion 18A approaches the first component portion 22. Therefore, the end portion 17A and the end portion 18A are further separated from each other, and a part of the tubular body 11 enters the second space B1 through the space between the end portion 17A and the end portion 18A. A part of the second arm portion 18 moves outside the first arm portion 17 in the thickness direction of the tubular body 11, and the engaging claw 26 and the engaging claw 28 are automatically engaged with each other.

Then, when the outer surface 11A of the pipe body 11 is brought into contact with the base portion 19 as shown in FIG. 5, the operator finishes the work of pressing the pipe body 11 against the insert clip 10, and the insert clip 10 holds the pipe body 11. become. That is, the insert clip 10 can position the tubular body 11 at a predetermined position with respect to the mating member 12, or can fix the tubular body 11 to the mating member 12.

In the state where the insert clip 10 holds the tubular body 11, even if a force is applied to the tubular body 11 in a direction for separating the tubular body 11 from the main body portion 13, a part of the first arm portion 17 is second. Since the engaging claw 26 and the engaging claw 28 are pressed against a part of the arm portion 18 and the engaging claw 26 and the engaging claw 28 are inclined, the engaging claw 26 is not released from the engaging claw 28. Therefore, the insert clip 10 maintains the state of holding the tube body 11.

In the insert clip 10 of the present embodiment, the operator causes the tubular body 11 to enter between the first arm portion 17 and the second arm portion 18 and presses the tubular body 11 toward the main body portion 13 (external force is applied). By performing one step work (one push), the first arm portion 17 automatically operates with the hinge 24 as a fulcrum, and the second arm portion 18 automatically operates with the hinge 27 as a fulcrum. The tube body 11 can be held in the first space B2 by the insert clip 10. That is, the first arm portion 17 and the second arm portion 18 operate in conjunction with the operation of pushing the tube body 11 toward the main body portion 13. Therefore, it is possible to reduce the work man-hours and work time of the worker, and it is not necessary to use a tightening tool, a driving tool, or the like.

Further, regardless of the diameter φ1 of the tubular body 11, the engagement amount between the engagement claw 26 and the engagement claw 28, that is, the engagement range of the first arm portion 17 and the second arm portion 18 in the arc length direction. Can be secured. Therefore, the function of the insert clip 10 to hold the tube 11 is stable. When the operator grasps the end portion 18B and elastically deforms the second arm portion 18 outward in the thickness direction of the tubular body 11, the engaging claw 28 is released from the engaging claw 26, and the tubular body 11 is moved to the first position. It can be taken out from the two spaces B1 and the first space B2.
