<p>A closing device with selective locking for closing a frame includes a roughly flat lid selectively applied to the frame, a lock connected with the lid, and a key which has a socket and an arm, one end of the arm carrying the socket. The lid has an opening for access to the lock by the key, the lock has a latch which cooperates with a catch of the frame, and the key selectively assumes, with respect to an opening, a locking position which the key can leave freely and in which the latch is trapped by the catch, and an unlocking position in which the key is trapped in the opening and in which the latch is disengaged from the catch. The arm and the socket of the key are roughly perpendicular to one another, and the arm is roughly perpendicular to the lid when the key is in the unlocking position.</p> |
