Locks and hasps

A lock for maintaining at least two lockable elements in a predetermined mutual arrangement, including first and second locking members which are mutually hinged together so as to be pivotable between a mutually open orientation and a mutually closed orientation and a key-operated locking mechanism for selectably locking the first and second locking members in the mutually closed orientation,

• the first and second locking members each including lockable element enclosing portions which are operative:
• when the first and second locking members are in the mutually closed orientation to maintain the lockable elements in the predetermined mutual arrangement and to prevent disengagement of the first and second locking members therefrom, and
• when the first and second locking members are in the mutually open orientation to permit disengagement of the first and second locking members from the lockable elements and to allow the lockable elements to be disengaged from the predetermined mutual arrangement,
• and wherein said first and second locking members are configured such that when they are in the mutually closed orientation their outer configuration generally defines first and second mutually fused spheres, one of the spheres including the lockable element enclosing portions and the other of the spheres including the hinge axis and the lock cylinder.
