Patent ID: 6983959

Claim:
A coupling for connecting hydraulic ducts, comprising: a first coupling element being a female coupling, said first coupling element having a receptacle and forming a first locking face arranged around a longitudinal axis of the coupling; a second coupling element being a male coupling, said second coupling forming a second locking face arranged around the longitudinal axis, and said second coupling element insertable in the direction of the longitudinal axis through an opening into the receptacle of the first coupling element; a holding element having a ring, and several cantilever spring elements formed on the ring and said spring elements extending parallel to the longitudinal axis; and locking elements formed onto free ends of the spring elements; said spring elements being, respectively, elastically deformable against a spring force radially out of a locking position into a releasing position; and in a connected condition of the coupling elements the first locking face and the second locking face facing one another and the locking elements being supported in the locking position of the spring elements on one side by the first locking face and on another side by the second locking face.
