ABSTRACT:
A fastening system is provided which includes an elongate grommet affixable into a correspondingly shaped aperture in a first object to be retained therein, and a clip passed through an aperture in a second object to be fastened to the first object. The two objects, one with the grommet affixed therein and the other with the clip projecting therethrough are brought together and, in a first orientation of the clip with respect to the grommet the clip is forcibly pressed into the grommet, whereupon a pair of claws formed onto the shank of the clip engage in an interference fit with recesses formed for such engagement into opposite walls of the grommet. The clip has a maximum transverse dimension smaller than an inside dimension of the elongate grommet, so that a predetermined amount of relative motion between the fastened objects is permitted by sliding motion of the clip while in interference engagement with the grommet.
