[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip comprising a pin and a grommet for connecting two members such as panels to each other.

[0002]

2. Description of the Related Art A grommet which is composed of a pin and a grommet is inserted into a hole of a member to be mounted such as two panels to which a grommet shaft is to be connected, and a pin shaft is inserted into a hollow shaft of the grommet. 2. Description of the Related Art A clip that enlarges a shaft portion and interconnects members to be attached to each other by the enlarged diameter shaft portion and a grommet flange is well known. With this clip, the members to be mounted can be connected to each other simply by inserting the grommet shaft part into the hole of the member to be mounted and pushing in the pin, so that the work is simple.

[0003]

When it is desired to release the connection of the mounted members, for example, when replacing the members mounted on the vehicle body, it is necessary to remove the clip from the mounted members. In removing the clip, the grommet is also pulled out by pulling out the pin. However, in many cases, only the pin is pulled out and the grommet remains on the member to be mounted. This is a configuration in which the attached members are connected to each other in a state where the grommet shaft portion is expanded, so if the connection portion is left for a long time, the grommet shaft portion is deformed to the expanded state and the pin is pulled out. This is because only the pin is pulled out without returning to the non-expanded state. If the grommet remains as described above, a grommet removal operation is added, and the grommet removal operation is troublesome.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a clip in which the grommet can be reliably pulled out by pulling out the pin even after the member to be mounted is long connected.
