Abstract: A fastener is disclosed which can be attached to a wall defining a polygonal aperture. A fastener face is adapted to abut a wall face near the aperture. A base element extends from the face to extend into the hole and abut opposed sides and corners of the hole. A shank comprises opposed planar surfaces oriented parallel to one another. Each surface is joined to the fasteners by a central stem, thereby defining two undercut shoulders on each face. At least part of the unflexed shoulder is spaced from the fastener face by a distance equal to or less than the hole thickness so as to secure the fastener in the hole.

Abstract: A PLASTIC CLIP FOR CONNECTING PERPENDICULAR PANELS. THE CLIP HAS A PLANAR HEAD PORTION WITH A REARWARDLY DIRECTED SHANK PORTION AND PRONG CONNECTOR ELEMENTS. THE REAR OF THE SHANK PORTION DEFINES A YIELDABLE THROAT AREA OPENING TO A SOCKET. THE SHANK PORTION OF THE CLIP IS INSERTED INTO AN OPENING IN ONE OF THE PANELS AND HELD IN THE OPENING BY THE PRONG CONNECTOR ELEMENTS. AN ARM ELEMENT IS SECURED TO THE OTHER PANEL AND THE PANELS ARE PERPENDICULARLY CONNECTED BY PRESSING THE ARM ELEMENT ON THE SECOND PANEL THROUGH THE YIELDABLE THROAT INTO THE SOCKET OF THE CLIP ON THE FIRST PANEL.
