Claim:
1. A walking surface having a fastening means comprising a beam and a locking member, the beam having a channel and locking extensions, the locking member having a base and an upstand, the base having reduced corners, the fastening means formed such that when it is in use the locking member can be slid into the channel and rotated in a first direction therein to assume a locking position, such rotation made possible by the reduced corners which serve to prevent a rotational impasse between the beam and the locking member, the locking member being in a tight fit within the channel and unable to pull out of the channel by reason of obstruction by the locking extension, the locking member being able to be released from the locking position only by rotation of the locking member in a second direction rotationally opposite the first direction, a walking surface board arranged such that the walking surface board is positioned onto one of the locking extensions wherein a part of the locking member extends into a side groove of the walking surface board, wherein a fixing member extends through the locking member to the beam to better secure the locking member to the beam.
