Patent ID: 7736107

Claim:
A clipping device comprising: an integral unit comprising: a pin; a grommet; and a plurality of bridges extending between the pin and the grommet, said plurality of bridges comprising a portion that is more fragile than a remainder of said bridge, said bridge having a width, wherein the width of the bridge is smaller at the grommet than at the pin, wherein: the pin includes an engaging groove, an enlarging groove, and a releasing groove on its outer peripheral face, in this order from a lower position, and the engaging groove at the lower position and the releasing groove at an upper position have smaller groove diameters than the enlarging groove at a middle position; the grommet includes a flange part at a top and a body part at a bottom, the body part being divided into a plurality of divisional leg portions with interposing slits, inwardly directed projections adapted to be engaged with the grooves of the pin on respective inner faces of the divisional leg portions; the grommet further includes a swinging piece connected to a side face of one of the divisional leg portions so as to swing in a radial direction of said grommet around a connecting part in the slit which divides the body part of the grommet; the pin further comprises a guide groove in an axial direction on an outer peripheral face of the pin corresponding to the swinging piece and a stepped part on the outer peripheral face of the pin at an upper end of the guide groove; the swinging piece is projected outwardly from the body part of the grommet while it is in a free state, and adapted to be pressed by inner peripheral faces of panel holes when inserted into the panel holes, thereby to be inwardly projected into the body part of the grommet; wherein the swinging piece is rotatably connected to said divisional leg portion so as to swing on or in a plane that is substantially normal to a longitudinal axis of the grommet, and wherein said plurality of bridges are located at respective circumferential positions corresponding to a position of each of said interposing slits.
