Abstract: A panel-framing assembly using clips to secure a pair of retaining strips to a frame member, along each edge of a panel being framed, without any adhesive. Each clip has a securing portion, which is insertable into a relatively wide region of a slot in a wall of the frame member, and which is adapted to coact with the wall to secure such clip to the frame member when such clip is moved so that the securing region is admitted by a relatively narrow region of the slot. Each retaining strip has an inner leg, which is insertable between a flanged portion of each clip and the wall when such clip is secured to the wall, and an outer leg, which is generally normal to the inner leg, and which is adapted to retain a panel seated against the flanged portion by engaging a portion of one face of the panel along one edge of the panel to prevent lateral movement of the panel relative to the frame member.

Abstract: A connector for cross-sectionally square, rectangular, hexagonal or other shaped tubes, including a solid cube-shaped block body having tapered arm members extending outwardly from its square sides; each arm having a spiral pipe screw thread therearound intercepted by elongated flutes so that the arm is cross-sectionally Greek cross-shaped with outwardly rib portions between the flutes, so as to be slidably fitted into a square or rectangular tube end or into the end of a hexagonal or other shaped tube with a square insert with the ribs being received in the corners of the square or rectangular tube or of the square insert whereby subsequent rotation of the tube causes the screw thread on the outer side of the ribs to cut an engaging thread on an inner side of the tube, or on the inner side of the square insert.
