Fastening means
Fastening means, a preferred embodiment of which is shown in FIG. 2, hasajoist 1 and a locking member 5. The joist 1 has a channel and locking extensions and the locking member 5 has a base 6 and an upstand 7. The base 6 has rounded corners 10. The fastening means is formed such that when it is in use the locking member 5 can be slid into the channel and rotated therein to assume a locking position, such rotation made possible by the rounded corners 10 which, when in use, serve to prevent a rotational impasse between the joist 1 and the locking member 5. The fastening means is formed such that when the locking member is in the locking position it is in a tight fit within the channel and cannot pull out of the channel by reason of obstruction by the locking extensions.
