A fitting includes a movable locking device connected to a lower fitting part for engaging an upper fitting part and thereby locking the fitting, a control cam for engaging with a control element of the upper fitting part and thereby controlling the engagement of the locking device and the upper fitting part, and a spring-loaded clamping eccentric that acts on the locking device for securing its engagement with the upper fitting part. For unlocking the fitting, the spring-loaded clamping eccentric is moved with an actuating force in a first unlocking step, so that the engagement of the locking device and the upper fitting part is removed. In the first unlocking stage, the control cam and the control element still engage. In a second unlocking stage, which is attainable with a higher actuating force, the engagement of control cam and control element is at least to a large extent is removed.
