Abstract (en)

[origin: DE19911208A1] The invention relates to a plug-in coupling (K) for connecting pipelines, hoses or similar, comprising a valve body (2) which is located in the first of two coupling elements (I, II) and which can be operated from the exterior, in particular, using a hand lever (1); and a locking sleeve (9) which can be displaced from a spring-loaded locked position that secures the interconnected position of the two coupling elements (I, II), into a release position. The coupling also comprises an additional valve body (7) which is located in the other coupling element (II). The invention aims to provide a secure solution which is also convenient to use. To this end, one of the valve bodies (2) overridingly causes the other valve body (7) to open at the edges, in the interconnected position.
