<p>A heater having a frame rail (50) and clips (40), attached to the rail, for securing insulators (60) for supporting a heater coil. Each clip has a main body having a structural member for securing to the rail, and having a pair of flanges (8.10) symmetrical about the central axis. Each flange has a cut-out (16) for supporting an insulator, the cut-out having an open end, a back abutment edge and a pair of side abutment edges. A bendable tab (20, 22, 24) is located at either side of the open end, each having a first and a second position. In the first position an insulator is insertable into the cut-out, and the insulator is secured by bending the tabs to their second position. Optionally the main body has a cross-section that accommodates the cross section of the rail (90) and the rail is welded to the channel (2). Alternatively, a plurality of clinching flaps (42, 44) extend from the main body, the flaps shaped and dimensioned for bending around and clinching the rail.</p> |
