Claim 0:
1. A coupling apparatus for a corrugated hose, having
a receptacle part for receiving the corrugated hose, and
a locking part, mounted on the receptacle part to be rotatable about an axis of symmetry of the coupling apparatus, for locking the corrugated hose in the coupling apparatus,
wherein the locking part has a resiliently deformable engaging element for interlocking engagement in a corrugation of the corrugated hose,
wherein the receptacle part has a receptacle region for receiving the engaging element,
wherein the coupling apparatus can be brought by means of a rotational movement of the locking part relative to the receptacle part from an unlocked state, in which the engaging element is arranged outside of the receptacle region, into a locked state, in which the engaging element is arranged within the receptacle region such that the receptacle region blocks a movement of the engaging element in a radial direction of the coupling apparatus, and vice versa,
wherein the receptacle part has a latching hook,
wherein the locking part has a first latching rib, in which the latching hook interlockingly engages in the unlocked state, and a second latching rib, in which the latching hook interlockingly engages in the locked state,
wherein the first latching rib and the second latching rib are arranged at a distance from one another along the axis of symmetry of the coupling apparatus, and
wherein the first latching rib and the second latching rib are designed as ribs extending completely around a base body of the locking part.
