The invention relates to a coupling device (1) for connecting and/or closing off fluid lines (60). The coupling device (1) comprises: A male coupling element (2) having a continuous recess (5) provided around the outer circumference and one radial projection (6); A female coupling element (3) having an arm (9) which comprises, at one end, an operating element (10) and, at an opposite end, at least one radially extending locking element (11). The female coupling element (3) further comprises a slot (108) that extends in axial direction and is a breather duct when the arm (9) is in the first position;A bayonet fastening which is formed by a labyrinth-like guide (12) in the wall (7) of the female coupling element (3) and the radial projection (6) of the male coupling element (2). The invention also relates to a line path and a line end section in which the coupling device (1) according to the present invention has been accommodated. |
