Abstract
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.
