<p>A box for electric material, comprising a box-shaped base (12) and a removable cover (13) adapted to close an aperture (40) of the base (12). The cover (13) has at least a tubular element (50) having an elastically deformable stop portion (52) adapted to assume an engagement position and a disengagement position with respect to a through hole (30) formed in the base (12). A slidable pin (60) is movable inside the tubular element (50) and interacts with the stop portion (52) for maintaining the same in engagement position. <IMAGE></p> |
