<p>A sliding window pickproof chain has a hinge mount (1), a connecting piece (2) and a bolt hook (3). The hinge mount (1) and the bolt hook (3) are placed on window frames respectively which are opposite to each other on an inside sliding window (4) and an outside sliding window (5). The bolt hook (3) is connected with the hinge mount (1) by the connecting piece (2). The pickproof chain has the least cost for pickproof function, and a complicated technical refitting is avoided for a new sliding window and an old sliding window.</p> |
