For detachably fastening inner and outer overlying plate members using a quarter-turn fastener, a square hole is punched in the inner panel and a snap-in receptacle assembly is inserted into the hole from the outer side of the panel and snapped into place. The receptacle assembly housing has six sides and is formed out of two components. The one component is a three-sided housing member having flange portions for bearing against the outer surface of the inner panel. The other component is a three-sided retainer member having spring legs which snap out behind the inner panel to lock the receptacle assembly in place. A compression spring inside the six-sided prism or housing has one end which bears against the front face of the retainer member and the other end bears against the fastener pressing it against rear face of the housing member and maintaining the housing and retainer members at spaced separation.
