A hasp lock has a casing to be mounted on a door and pivotally mounted to be displaceable between a first position, in which the casing overlies a securing structure mounted on a door frame with a cylinder lock operable to lock the casing to the securing structure, and a second position to which the casing can be pivotally moved when the cylinder lock has been unlocked so that the door may be freely opened and closed.
