Abstract
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, 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, the receptacle part having a receptacle region for receiving the engaging element, wherein the coupling apparatus can be brought by means of a 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.
