ABSTRACT:
A stud clip adapted for mounting upon an upstanding threaded bolt or stud comprises a pair of oppositely disposed latch members having a plurality of claw or detent portions defined thereon for engaging the threaded shank portion of the stud or bolt. The latch members may have a predetermined thickness, or may be tapered, in order to provide the stud clip with a relatively low or small insertion force, however, in order to concomitantly provide the stud clip with a relatively high or large retention, removal, or withdrawal force, spring members are provided adjacent to the latch members so as to bias the latch members into forceful engagement with the threaded shank portion of the stud or bolt once the stud clip is mounted upon the stud or bolt, or alternatively, once the stud or bolt is inserted into the interior cavity of the stud clip. The spring members are initially spaced from the latch members, until the stud or bolt expand the latch members radially outwardly into engagement with the spring members, so as not to interfere with or compromise the relatively low or small insertion force.
