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 ().

Coupling for connecting hydraulic ducts

A coupling for connecting hydraulic ducts has a first coupling element (), in the form of a female coupling, with a receptacle () and a first locking face (), and a second coupling element (), in the form of a male coupling, The second coupling element () has an annular groove () that forms a second locking face () insertable into the receptacle (). Several locking elements () are arranged in the annular groove (). The locking elements () are held in the annular groove () and can be pivoted between a locking position and a releasing position. In the coupled condition of the coupling elements (), the first locking face () is axially supported on the second locking face (). An unlocking sleeve () is displaceable between a locking position and a releasing position on the second coupling element (). By moving the unlocking sleeve () from the locking position into the releasing position, the locking elements () are displaced from the locking position into the releasing position.
