A nail 13 is provided. FIG. 10 shows a state in which the pipes 14 are held in parallel as parts to be attached.

FIG. 11 shows the rear cover 9. The rear cover 9 has substantially the same structure as the front cover 8, with openings 9b formed at substantially equal intervals in the main body 9a, and a coupling portion 9c for coupling with the front cover 8 formed at the front end. The rear cover 9 has substantially the same structure as the front cover 8, and will not be described in further detail. At a position near the rear end of the rear cover 9, an engaging portion 10 for engaging with the clamp 1 is formed similarly to the front cover 8.
The engaging portion 10 has the same shape as the engaging portion 10 formed on the front cover 8. Further, a cover-side holding portion 11 having the same shape as the holding portion 11 of the front cover 8 is formed at each of the front and rear portions of the engagement portion 10.

When a clamp device composed of the clamp 1, the front cover 8 and the rear cover 9 is used, the front cover 8 and the rear cover 9 are connected to the connecting portions 8c, 9
and the clamps 1 are attached to the respective engaging portions 10. In this case, the locking claw 7 formed on the outer surface of the component holding portion 4 of the clamp 1 is engaged with the locking hole 10d of the engaging portion 10. Next, components such as the pipe 14 are attached to the component holding portions 4 of the clamp 1 and the concave grooves of the cover-side component holding portions 10 of the front cover 8 and the rear cover 9.

In this state, the screw grommet 3 formed on the mounting portion 2a of the clamp 1 is inserted into the hole of the panel. At this time, the locking pawl 3c for temporary fixing formed on the outer surface of the wide leg 3a of the screw grommet engages with the panel to perform temporary fixing. Next, a screw hole 10d formed in the engaging portion 10 of the cover 8, 9 and the mounting portion 2 of the clamp 1

b is expanded outward in the radial direction, and the screw grommet 3 is securely held on the panel.

With the mounting structure in which the tap screw is screwed into the screw grommet, there is no possibility that the mounting will be loosened by creep. However, the use of a tap screw is not essential to the invention. Further, the screw grommet may be of a type having a bag-like leg portion which can be expanded in the radial direction by inserting a screw. The use of the screw grommet provided with the bag-shaped legs can provide water tightness. Further, the screw grommet does not need to be integral with the clamp, and is included in the scope of the present invention, in which the screw grommet is formed separately from the clamp, and is attached to the panel by screwing the cover and the clamp together with the screw.

In the present invention, the clamp, the screw grommet, and the cover are all formed by molding a synthetic resin.

[0017]

As described above, in the present invention, since the clamp is attached to the panel by the screw grommet and the clamp cover is attached to the clamp, it is not necessary to weld the nut to the panel in advance. Also, there is no need to use a metal stay for mounting. Therefore, the number of parts can be reduced, the mounting work is simple, and the weight is low.
