a first fitting part and a second fitting part, the first fitting part and the second fitting part are each rotatable relative to each other about an axis of rotation;
four locking elements movably mounted relative to the first fitting part and configured to move to a locking position, in which each of the four locking elements engage a toothing of the second fitting part, wherein each of the locking elements includes a primary support protrusion; and
a cam element, rotatably mounted relative to the first fitting part, and including a plurality of cams configured to support the four locking elements disposed in the locking position so that the primary support protrusion of each of the locking elements is in contact with one of the cams of the plurality of cams at a respective support point of four support points,
wherein each of the four locking elements disposed in the locking position contacts the cam element only with its primary support protrusion when no force is acting on the first and second fitting parts and
wherein two support points of the four support points, that support the primary support protrusions of two adjacent locking elements of the four locking elements, are arranged closer to each other than to the other two support points of the four support points and than the other two support points of the four support points are to each other.
