The invention provides a removeable retainer (23) held within a cavity formed between a face plate (4) of the handle assembly and the door, and adapted to act between the handle (1) and an internal surface of the face plate to prevent rotation of the handle (1). The retainer (23) is held in place in part by a two piece spindle (22), each piece (22A, 22B) being freely rotatable about the other, such that one piece (22B) can be anchoured into the retained handle (1), whilst the other (22A) is free to be rotated by an opposing handle (17) so as to actuate the latch or lock mechanism. The invention enables, at the installer's discretion, to fix the position of one of the handles such that it cannot be used to actuate the latch or multipoint lock, such that once the door is shut it cannot be opened, e.g. from the outside, without a key. |
