摘要

A positioning device is provided for securing an object to a fixing plate having a plurality of positioning holes. The positioning device includes a cover plate having a side with a plurality of engaging posts extended from the side. Each engaging post includes a conic distal end with an enlarged annular shoulder, each engaging post including a transverse slot that extends over the annular shoulder. The annular shoulder is compressed and passed through an associated positioning hole and then expands into its original shape so as to be retained to an underside of the fixing plate in an area surrounding the associated positioning hole, thereby securing the object between the cover plate and the fixing plate.
