Abstract
A coupling for connecting hydraulic ducts has a female coupling () with a receptacle and a first locking face arranged around a longitudinal axis. A male coupling () forms a second locking face, arranged around the longitudinal axis. The male coupling () can be inserted in the direction of the longitudinal axis () through an opening into the receptacle (). A holding element () has a ring () with several spring elements projecting from the ring (). The spring elements () extend parallel to the longitudinal axis (). Locking elements () are formed on the free ends of the spring elements (). The spring elements () are, respectively, elastically deformable against a spring force radially out of a locking position into a releasing position. In the inserted condition of the male coupling (), the first locking face () and the second locking () face one another. Also, the locking elements () are supported in the locking position of the spring elements () on the first locking face () and on the second locking face ().
