ABSTRACT:
A locking device is provided with a padlocking arrangement which includes a shiftable or pivotable latch lever cooperating with at least one padlock member, and a padlocking enabling member fit on a shaft of square cross-section connected to an electromechanical equipment to be controlled and inserted into a bore formed in a hub of a rotating control handle. The bore is formed by two superimposed circumferentially offset square openings receiving the shaft with clearance to permit a slight angular movement of the shaft and the padlocking enabling member thereon to cause disengagement of the latch lever from the padlocking enabling member.
