<p>The rail has side faces (4) connecting a support face (8) to a fixing face (2), where each side face carries a pair of hooks (12) at an end face (10). The hooks extend toward outside the rail along longitudinal direction of the rail. A face among the support face, fixing face and the side faces carries a pair of slots (14) sized and arranged such that the slots cooperate with the hooks. The hooks are formed in L-shape and connected to a corresponding side face by a folded tab such that the hooks extend in a plane parallel to the side faces, and are off-set toward interior of the rail.</p> |
