The holding portion 24 for holding the locking bar 22 has a pair of axially extending ribs 26 formed inside thereof so that the inserted pin leg portions 8, 8 can straddle the locking bar 22 as they are. And also functions as a stopper that prevents the pin from being pushed deeper than in FIG. 16 even if the pin is pushed in. The elastic locking pawls 1 of the pin leg portions 8 are provided on the shaft portion 21 at the first locking position shown in FIGS.
Slits 27, 27 from which 5, 15 extend to the outside are formed from the intermediate height position toward the flange 20. A recess 28 is formed in the flange 20 on the extension of the slit 27 so as to receive the projection 17 of the pin head 7.

FIG. 1 shows a state in which the pin 2 and the bush 3 having such a structure are connected to each other at a first locking position. To connect to the first locking position, the pin 2 is connected to the bush 3
May be inserted into the hollow shaft portion 21. That is, pin 2
Is inserted into the bush shaft portion 21, the rib 26 guides the legs 8, 8 of the pin 2 so as to straddle the locking bar 22, and the first locking portion 9 at the tip of the pin leg 8 is locked by the locking bar 22. Since the pin 22 is received and locked, the insertion of the pin 2 may be stopped here.
In this first locking position, the pin 2 and the bush 3 are connected but the shaft 21 of the bush 3 does not expand. In the first locking position, the pin head 7 protrudes from the bush flange 20 by a certain height, so that the operator can work by pinching the protruding portion. In the first locking position, the elastic locking claw 15 of the pin leg 8 extends outside through the slit 27 of the bush shaft 21. The connected state at the first locking position is the delivery, transport, and storage state of the clip 1. In the illustrated example, the first locking state is the first locking state of the pin 2.
Although the description has been made on the assumption that the locking portion 9 is locked by the locking bar 22 of the bush 3, the tip of the pin 2 is projected outward in the radial direction so as to lock on the tip of the shaft portion 21 of the bush 3. Although the pin 2 and the bush 3 are connected, the diameter of the shaft 21 of the bush 3 may not be increased.

When the clip 1 is inserted into the mounting hole 29 of the mounting member 4 until the bush flange 20 comes into contact with the front end of the pin leg 8 as the leading end, the front end of the elastic locking claw 15 protruding outward from the bush shaft 21. Project from the back surface of the mounting member 4 and are locked, so that the clip 1 is held by the mounting member 4. This temporarily fixed state is the state of transport, delivery and storage of the mounting member with clip.

The attachment member 4 with a clip shown in FIG. 13 is transported to a place such as an outfitting line of an automobile, and is attached to a panel 5 such as a vehicle body with the clip 1 attached as shown in FIG. In this mounting operation, since the clip 1 has already been mounted, it is not necessary to support the clip 1 with a finger, and the decorative member 4 can be positioned on the panel 5. Work such as alignment is not required, and positioning can be performed easily. As shown in FIG. 14, when the decorative member 4 is pressed against the panel 5, the pin leg 8 and the bush shaft 21 of the clip 1 are inserted into the mounting holes of the panel 5. The wire is retracted as shown by the solid line from the projecting position of the line (note that the wire is not necessarily retracted at the position shown in FIG. 14). From the state of FIG. 14, as shown in FIG. 15, the pin 2 is pushed strongly from above the head 7. By this pushing, the second locking portion 10 of the pin leg 8 comes into contact with the locking bar 22 at the tip of the bush shaft portion. This contact is made by the second locking portion 10
The legs 8, 8 are opened, and the legs 25, 25 of the bush shaft 21 are also opened by the legs, thereby expanding the diameter of the bush shaft. This opened state is the second locking position. By expanding the bush shaft portion in this way, the panel 4 and the panel 5 are connected to the bush shaft portion 21.
Are connected to each other by an enlarged diameter portion and the flange 20. The elastic locking claws 15, 1 and 1 are pushed by the pin 2.
