ABSTRACT:
A security bar 14 for securing a door 2 hinged at one side of a door 2, the security bar 14 being hinged to the door surround 4 at the same side as the door 2 is hinged thereto and extending across the door surround 4 so as to be lockable with a locking device 18. The bar 14 is of freely adjustable length, and has its lockable end fixed relative to the door 2. Thus, the door 2 and the bar 14 pivot together about their respective displaced hinges by virtue of the varying length of the bar 14. The locking device is in the form of a key operated lock, the key of which is long enough to pass through the thickness of the door and into the lock.
