<p>A connector 1 has an elongate base member 2 with at least one fixing receiving aperture 3A,3B. A projection 4 extends from one face of the base member 2 to engage with a connector recess. An elongate key plate 5 is spaced from an opposing face of the base member 2 forming a groove between the key plate 5 and the base member 2, the key plate 5 being normal to the base member 2. In use the key plate 5 is insertable through a key plate shaped aperture in a rectangular tube wall and rotated by rotating the base member 2 whereby the tube wall is sandwiched between the key plate 5 and base member 2 and free ends 5B of the key plate 5 abut side walls of the rectangular tube. A fixing is located in the fixing receiving aperture 3A, 3B which prevents the base member from rotating.</p> |
