The plug of a key-operated locking device is formed in two parts, namely an outer housing which is formed with slots to receive springs which act on tumblers of the device and an inner matrix formed with slots to receive the tumblers. The two parts are locked together by, for example, one of the staking bars normally used as abutment members for the tumbler springs.
