摘要

A box for protecting an electric meter or similar apparatus against fraud, theft and the like comprises a hollow body (1) provided with an aperture (2) and a cover (3) adapted to close the aperture (2) of the body (1). The cover (3) carries a locking mechanism (29) operable by a key (33) and provided with a locking member (34) rotatable with respect to cover (3) between a locked position in which the member (34) engages retainers (37) of the body (1) and a release position. The locking mechanism (31) allows removal of the key (33) when the locking member (34) is in the locked position and unremovably retains the key (33) when the locking member (34) is in the release position. The box comprises spring loaded bolt means (43) for irreversibly maintaining the locking member (34) in the locked position when the locking member (34) and the retainers (37) are mutually engaged. <IMAGE>
