A coupling arrangement (12) with a housing (6) has a first locking part (18), a locking element (14) and a ring (16), which is arranged intermediate the locking element (14) and the housing (6). The locking element (14) is cylindrical having a center axis (X) and has a second locking part (28) and at least one locking contour (30) having a first end (32) designed to take in a respective pin (34) of a connecting element (36) to disable rotational movement of the connecting element (36) via positive locking. The ring (16), the first locking part (18) and the second locking part (28) are designed and arranged such as to form a positive locking at least in one direction of the center axis (X) between the housing (6) and the locking element (14) via the ring (16).
