An engagement convex portion is formed in a grommet of a two-piece clip, and a head portion-side engagement concave portion is formed in a pin of the two-piece clip. When the pin is pushed into the grommet to a maximum push-in position, an inner end of the engagement convex portion of the grommet abuts against a middle of a tip-side concave portion wall surface of the head portion-side engagement concave portion. Thus, in the maximum push-in position, when a tip portion of the pin is pushed back in an extracting direction, the tip-side concave portion wall surface of the head portion-side engagement concave portion of the pin slides against the inner end of the engagement convex portion of the grommet. |

1. A two-piece clip assembly, comprising:
a grommet including a body portion adapted to be inserted into attachment holes of overlapped members and split through at least two slits extending from a tip portion of the body portion to a base portion thereof, the body portion having an engagement convex portion formed at the tip portion and including a tip-side convex portion wall surface inclining inwardly upwardly in a direction from the tip portion of the body portion toward the base portion thereof and a base portion-side convex portion wall surface inclining outwardly upwardly from the tip-side convex portion wall surface, and a base part formed at the base portion of the body portion and adapted to abut against a peripheral edge portion of the attachment holes of the members, the base part having an insertion hole; a pin including an axis portion inserted into the insertion hole of the body portion of the grommet, and a head portion provided in one end portion of the axis portion, the axis portion having a tip-side engagement concave portion engaging with the engagement convex portion of the grommet in a standard position where the pin is inserted into the insertion hole of the grommet to elastically deform the body portion of the grommet outward so as to clamp the members through the body portion and the base portion, and a head portion-side engagement concave portion formed between the tip-side engagement concave portion and the head portion, and engaging with the engagement convex portion of the body portion in a maximum push-in position where the pin is inserted into the insertion hole of the grommet further than the standard position, to elastically return the body portion of the grommet inward so as to pass through the attachment holes, the head portion-side engagement concave portion including a tip-side concave portion wall surface inclining inwardly upwardly in a direction from another end portion of the axis portion toward the one end portion thereof, and a head portion-side concave portion wall surface inclining outwardly upwardly from the tip-side concave portion wall surface, wherein in the maximum push-in position, an inner end of the tip-side convex portion wall surface of the engagement convex portion abuts against a middle of the tip-side concave portion wall surface of the head portion-side engagement concave portion, and the tip-side concave portion wall surface of the head portion-side engagement concave portion of the pin has an inclination angle relative to an axis line of the pin narrower than an inclination angle of the tip-side convex portion wall surface of the engagement convex portion of the grommet relative to the axis line of the pin to form a gap between the pin and the grommet in the maximum push-in position. |
