<p>The present invention provides a lockable handle assembly for a window or door comprising: a handle member, the handle member having a lockable position to lock a window or door, the handle member being moveable away from the lockable position in order to open the window or door; a handle mounting to which the handle member is pivotally connected ; a locking device having a locked condition for preventing movement of the handle away from the lockable position and an unlocked condition for allowing movement of the handle away from the lockable position and being resiliently biased to the locked condition, wherein the locking device is exposed to be demountable from the handle assembly when the handle member is turned substantially beyond its normal operational angle of opening movement but is otherwise trapped by the handle mounting against removal.</p> |
