A locking arrangement for a door includes an upright operating bar mounted on the door for angular movement about its axis and a handle which is connected to the operating bar by a pivotal connection for engagement with a closure mechanism. A tongue having a rack can extend from a first module into a cavity formed in the second module. A number of the stages are coupled in series, the output of one feeding the input of the next, to form the ring.
