<p>Box (1) for fastening in a hole of a hollow wall. The box comprises a bottom, consisting of substantially complementary first (2) and second (12) portions, and a wall, consisting of first (4) and second (14) portions, defining a space (24) in which material of an electrical installation can be fitted. On the outer side, the second wall portion has a nozzle (16). The second bottom portion (12) and the second wall portion (14) with the nozzle (16) form a nozzle part (6). The wall portions are integrated via a hinged portion (8) having an axis parallel to the bottom. Along their free edges, the bottom portions (2, 12) have locations of such dimensions that, when the bottom portions extend substantially in one and the same plane, the bottom portions secure each other. On the second bottom portion a lip (26) is formed, with which, after the box has been installed in the hollow wall, the nozzle part can be pulled back into the space.</p> |
