This allows in addition to a simple exchange and easy to betechnikstelligende retrofitting a coupling device. An adaptation to the locking device is not required. Due to the independence of coupling device and locking device, an existing fitting can be maintained. Thus, a cost-effective retrofitting of existing locking devices is possible.
