<p>The case (C) has fixation units e.g. fastening screw, forming an integral part of bottom and top horizontal walls (10, 14) and lateral walls (11, 12), and a homologous mounting unit for ensuring blocking of the walls from edge to edge in two orthogonal directions (X, Y). A homologous engaging unit ensures blocking of the walls from the edge to edge in a third direction (Z) that is orthogonal to the directions (X, Y). The mounting and engaging units assure auto-locking of the walls by bringing the edges of the walls together during assembling of the walls.</p> |
