LOCK WITH TWO LOCKING HOOKS AND WITH PROTECTION AGAINST UNAUTHORIZED USE
Lock comprising: a housing, two locking hooks rotationally coupled with the housing and provided each provided with a locking jaw; a blocking drum arranged so that in order to allow any of locking or unlocking operations is acted upon so to retract from the position where it blocks the rotational movement of the two locking hooks and in order to block any of locking or unlocking operations it is acted upon so to reenter the position where it blocks the rotational movement of the two locking hooks; and at least one spring which permanently biases the two locking hooks one towards another in the area of their locking jaws; whereto each of the locking jaws has an outer flank and an inner flank, which have profiles of whose tangents at the contact points with a striker of a locking object form each an acute angle with the direction of insertion or removal of the striker so to allow the striker to disjoint the two locking jaws when sliding between them during locking and unlocking operations.
