A closure device is provided. The closure device includes a first closure element, a second closure element, which can be arranged on the first closure element in a fixing direction and which is connected to the first closure element in a closed state, and at least one actuating element, which is movably arranged on the second closure element. The at least one of the closure elements has a receptacle into which the other closure element can be shoved at least partially. The second closure element in the closed state is held on the first closure element via the actuating element and for this the second closure element interacts with the actuating element, while in an unloaded state the second closure element can be loosened from the first closure element by activating of the actuating element.
