Both holders (12,14) are identical in shape, and, together with the connecting tube, have a device (64,66) for accurate angle orientation to each other. The device comprises guide surfaces on the tube ends, and similar surfaces on the hole (46) accommodating the holder tube, the surfaces being inclined in order to match each other with those on the tube (64) aligned. The connecting tube (16) comprises an inner tube of metal (60), and one outer of plastic (62). The holders (12,14) are fastened to the tube by a nail (74) which is drawn through the holder surrounding part, through the plastic tube, is bent over by the metal tube (60) so that it re-enters the plastic tube, and through the hole wall back out into the holder. The holders incorporates a connecting and contact wire (28) which in turn has a light tube contact part (30), a connecting body (32), and a contact arm (34) for an igniter (18). |
