A mortise lock (10) including a mortise lock case (12) which houses a locking mechanism actuable by a key-operated lock cylinder (14), and separately by a handle (16) which engages a bolt follower (19) in operative connection with the locking mechanism, characterized in that the mortise lock (10) comprises a plurality of locking bolts (20, 22, 24, 26, 30, 32, 34) which are arranged to protrude outwards from the case (12), and wherein the handle (16) is operatively linked to the plurality of locking bolts (20, 22, 24, 26, 30, 32, 34) by a linkage wherein the plurality of locking bolts (20, 22, 24, 26, 30, 32, 34) are actuable into an unlocked position by suitable rotation of the handle (16) independently of whether or not the mortise lock (10) is locked by the key-operated cylinder. |
