A locking structure comprising a channel and a bracket. The channel has a pair of lips defining an elongated mouth. The bracket is L-shaped having a horizontal limb and a vertical limb extending downwardly from one end of the horizontal limb. The bracket has a neck the lower end of which merges with said vertical limb. The neck extends obliquely upwardly from said vertical limb and has a locking formation at its free end. The locking formation is wider than the neck and projects laterally on each side of the neck. The neck can pass through the mouth. When the bracket is so positioned with the neck passing through the mouth, the laterally projecting parts of the locking formation engage one face of each lip. The external surface of the vertical limb engages the other face of each lip. Said one face of each lip is formed with deformable serrations which extend in the direction of elongation of the mouth. |
