Further, near the end of the strip portion 8 on the first locking portion 9 side, a rectangular hole 14 is provided to make the strip portion 8 easier to curve.
There are several.

The connecting portion 10 is flat and has the same thickness as the strip portion 8, and is narrower than the strip portion 8.

The first locking portion 9 has the same thickness as the strip portion 8, and a first strip insertion hole 15 is provided in the first locking portion 9. A serrated first locking protrusion 16 is provided on the inner surface of the first strip insertion hole 15.
is provided, and this locking protrusion 16 allows the belt-like part 8 to be inserted into the entrance of the first belt-like part insertion hole 15 when the belt-like part 8 is inserted into the first belt-like part insertion hole 15 as shown in FIG. The serrations allow movement from the side (the front side of the first locking part 9) toward the exit side (the back side of the first locking part 9), but do not allow the movement in the opposite direction. It is adapted to engage with the protrusion 13.

A second belt-like part insertion hole 17 is passed through the second locking part 11 from the belt-like part 8 toward the base part 12 . The height of this second band-shaped part insertion hole 17 is
As shown in FIGS. 2 and 7, the height becomes lower as it goes from the inlet side (belt-shaped part 8 side) to the outlet side (base part 12 side).

A locking piece 18 is provided on the exit side of the second band-shaped part insertion hole 17. This locking piece 18 has three free ends, and only one end is continuous with the other part of the second locking part 11 in the vicinity of the second band-shaped part insertion hole 17, and this locking piece A groove 30 is provided between the second locking portion 18 and the other portion of the second locking portion 11 . A serrated second locking protrusion 19 is provided on the inner surface of the locking piece 18, and this locking protrusion 19
Normally, when the strip 8 is inserted into the second strip insertion hole 17 as shown in FIG. 7, the strip 8 is directed from the inlet side to the exit side of the second strip insertion hole 17. It is designed to engage with the serrations 13 in such a way that it is allowed to advance in the past but not allowed to advance in the opposite direction.

Further, on the outer surface side of the locking piece 18, that is, on the back side of the locking projection 19, a locking release projection 20 is provided.
is provided. The base portion 12 is provided with a screw insertion hole 21 in a direction perpendicular to the second strip insertion hole 17 .

This fixture 7 can be used by cutting the connection part 10, or can be used without cutting the connection part 10. Next, how to use this fixture 7 will be explained first, starting with how to use it without cutting the connection part 10.

As shown in Figure 7, the mounting screw 22 is inserted into the screw insertion hole 21.
This mounting tool 7 is attached to the support body 4 by inserting the attachment screw 22 into the support body 4.

On the other hand, the strip 8 is wound around an attachment object 23 such as an electric wire as shown in FIG. 6, and the strip 8 is inserted into the second strip insertion hole 17 as shown in FIGS.
Then, it is inserted into the insertion hole 17 from the entrance side to the exit side. Then, if the tip of this band-shaped portion 8 is further strongly pulled, the second locking protrusion 19 is released as described above.
The serrated protrusion 13 allows the band 8 to advance from the entrance side to the exit side of the second band insertion hole 17, but does not allow it to proceed in the opposite direction.
As a result, the strip portion 8 is locked to the second locking protrusion 19 in a state where the attachment target 23 is strongly tightened. Thereby, the attachment object 23 is securely attached to the support body 4 via this attachment tool 7.

In this attachment 7, in the case of use as described above, one of the many serrated protrusions 13 is connected to the second locking protrusion 19 depending on the thickness of the attachment target 23.
By being locked to, objects 23 having a wide range of thickness can be attached to the support body 4 using the same attachment 7.

In addition, in this fixture 7, the connecting portion 10 is flat and narrower than the strip portion 8, so the connecting portion 10 can be easily removed with a nipper or the like as shown on the line B-B in FIG. By cutting, this fixture 7 is divided into two parts: a part consisting of the strip part 8 and the first locking part 9, and a part consisting of the second locking part 11 and the base part 12.
It can also be divided into two parts and used in the manner shown in FIGS. 8 and 9.

That is, the part consisting of the second locking part 11 and the base part 12 is connected to the screw insertion hole 21 as in the above case.
It is attached to the support 4 by inserting a mounting screw (not shown) into the support 4 and screwing the mounting screw into the support 4.

On the other hand, the band-shaped part 8 is wound around the attachment target 23 and is inserted with the tip side of the first band-shaped part insertion hole 15 from the entrance side to the exit side. Then, if the tip of the strip 8 is further strongly pulled, the first locking protrusion 16 will cause the strip 8 to move from the entrance side to the exit side of the first strip insertion hole 15 as described above. It engages with the serrated protrusion 13 in such a way that it is allowed to advance, but not allowed to advance in the opposite direction, so that the band-shaped part 8
is locked to the first locking protrusion 16 in a state where the attachment target 23 is strongly tightened.

Then, the second strip part insertion hole 17 is further inserted into the distal end side of the strip part 8 from the entrance side to the exit side, and the serrated protrusion 13 on the distal end side is locked with the second locking protrusion 19. By doing so, the attachment object 23 can be attached to the support body 4 via the two parts of the divided attachment tool 7.

Here, in the first method described in which the connection part 10 is used without being disconnected, the base part 12 is connected to the support 4.
If it is attached to the object 23 first, it will be difficult to wind the band 8 around the object 23, and conversely, the object 23 will be attached to the object 23.
If the band-like part 8 is wound around the support body 3 first, it may become difficult to attach the base part 12 to the support body 4, but it is possible to cut the connecting part 10 as shown in FIGS. In this case, the part consisting of the band-shaped part 8 and the first locking part 9 and the part consisting of the base 12 and the second locking part 11 are separated, so that the support body 4 is Both the attachment of the base portion 12 and the winding of the strip portion 8 around the object to be attached 23 can be performed extremely easily.

In addition, when the connecting part 10 is cut and used in this way, by selecting the position of the serrated protrusion 13 that engages with the second locking protrusion 19, the distance between the base part 12 and the attachment target 23 can be adjusted. can be changed freely.

Furthermore, even when the connecting portion 10 is cut and used in this way, one of the many serrated protrusions 13 is locked to the first locking protrusion 15 depending on the thickness of the attachment target 23. Therefore, objects 23 having a wide range of thickness can be attached using the same attachment 7.

In addition, in this fixture, since the unlocking protrusion 20 is provided on the back side of the second locking protrusion 19, in either of the above two usage methods, the strip part 8 can be attached to the second strip part. Even if it is inserted into the insertion hole 17 once, if the locking release protrusion 20 is pushed in the direction of arrow A in FIG. 7, the locking piece 18 will be raised.
The engagement between the second locking protrusion 19 and the serrated protrusion 13 is released, and the second strip part insertion hole 1 of the strip part 8 is released.
7 from the outlet side to the inlet side, and can be easily extracted from the insertion hole 17.

Further, the locking piece 18 has three free ends, and only one end is continuous with the other part of the second locking part 11 near the second band-shaped part insertion hole 17, and this locking piece 18 has free ends on three sides. Since a groove 30 is provided between the piece 18 and the other part of the second locking portion 11, when the engagement between the second locking projection 19 and the serrated projection 13 is released, Just by lightly pushing the unlocking protrusion 20, the locking piece 18 is raised and the engagement is released. Therefore, the engagement can be easily released.

In addition, in this embodiment, when attaching the strip part 8
Since the surface on which the serrated projections 13 are not provided comes into contact with the attachment target 23, the serrated projections 13
Therefore, the attachment target 23 is not damaged.

Furthermore, in the embodiment described above, the base is attached to the support body with a mounting screw, but
It goes without saying that in the present invention, the base may be attached to the support by other means.

Furthermore, it goes without saying that the object to be attached in the present invention is not limited to electric wires, but may be any arbitrary object, and the support may also be any arbitrary object.

As described above, the fixture according to the present invention includes a strip portion 8 having a large number of serrated projections 13, a first locking portion 9 having a first strip insertion hole 15 and a first locking protrusion 16. , a second locking part 11 having a second belt-shaped part insertion hole 17, a locking piece 18 and a second locking protrusion 19, a first locking part 9 and a second locking part 11. Connect. By integrally having a flat connection part 10 which is narrower in width than the strip part 8 and can be cut, and a base part 12 which is attached to the support body 4, (a) one type of fitting can be used for various thicknesses. The attachment object 23 can be attached to the support 4.

(b) Since the connecting portion 10 is flat and narrower than the strip portion 8, the connecting portion 10 can be easily cut to form a portion consisting of the strip portion 8 and the first locking portion 9; The portion consisting of the base portion 12 and the second locking portion 11 can be made into separate bodies.

When using the connecting portion 10 without cutting it, if the base portion 12 is attached to the support 4 first, it becomes difficult to wind the strip portion 8 around the attachment object 23; If the band 8 is wound around the support body 23 first, it may become difficult to attach the base part 12 to the support body 4. However, if the connection part 10 is cut as described above, Attachment of base 12 and attachment target 2
Both the winding and winding of the band-shaped part 8 around the belt 3 can be carried out extremely easily. In addition, in this case, the serrated protrusion 1 that engages with the second locking protrusion 19
