The spring means 4e is formed on both sides of the base portion 4 with the shaft-like main body 3 interposed therebetween and on the side where the insertion portion 1 is formed. In the illustrated example, the spring means 4e is an elastic strip 4f having an arch shape in which both ends of the piece are integrally connected to the base 4 and the middle portion of the piece extends in an arc shape. The pitch in the insertion direction of the insertion portion 1 between the middle portion of the elastic strip 4f and the anti-rotation projection 1e is set to be smaller than the thickness of the fastening object P.

  On the other hand, the anti-rotation protrusion 1e is formed on the side of the pair of branch portions 1b and 1b facing the base portion 4, respectively.

  The anti-rotation recess Hc is formed on the surface of the insertion destination side Fw of the insertion portion 1 into the through hole H in the fastening object P. In the example shown in the drawing, the rotation-preventing recess Hc is formed on both sides of the wide portion Ha 'of the through hole H.

  According to such a configuration, after the insertion portion 1 has been inserted into the through hole H of the fastening object P, the rotation preventing protrusion 1e is inserted into the through hole H of the fastening object P on the surface of the insertion destination side Fw. The twisting operation can be performed while elastically deforming and pressing the spring means 4e. When the anti-rotation protrusion 1e reaches the position where it enters the anti-rotation recess Hc by such a twisting operation, the anti-rotation protrusion 1e enters the anti-rotation recess Hc by the elastic return of the spring means 4e, and the direction in which the above-mentioned catching of the branch portion 1b is released. Rotation to is prevented. Thereby, the fastening state of the clip C with respect to the fastening object P is maintained stably. In this fastening, the anti-rotation protrusion 1e is not damaged by the hole edge of the through hole H. From this state, the clip C is again twisted to the position before the twisting operation while elastically deforming the spring means 4e so that the anti-rotation protrusion 1e is pulled out of the non-rotating recess Hc. The date is solved.
