ABSTRACT:
A push to install, quarter turn to release fastening system includes a fastener having a plurality of radially extending frustum-shaped projections spaced along a shank and a pair of diametrically opposed ribs extending along the shank forming smooth surfaces outside the periphery of the frustum-shaped projections. The receptacle includes a split cylinder forming a pair of spring latches that are displaced to permit entry and captivation of the fastener. When the fastener is turned 90.degree., the ribs displace the spring latches to positions out of engagement with the frustum-shaped projections to enable removal of the fastener from the receptacle.
