  • Patent number: 3965776
    Abstract: A tool for installing a retainer clip on a headed stud, the clip including an upstanding forward flange and a central upturned stud engaging portion, the tool having a pair of longitudinal pusher prongs that are vertically offset from each other and provided with undercut areas on the inner sides of each prong terminating at a forwardly sloping bevel wall section on each prong. The lateral spacing of the prongs and the undercut areas are preferably dimensioned to accommodate different size clips, with the bevel wall sections engaging the edges of the upturned central portion of the larger size clip to be installed by the tool. The forward extremities of the prongs engage the upstanding forward flange of the clip and the prongs are vertically offset slightly at their extremities to enable the clip to be frictionally retained on the prongs during the installation operation.
