摘要：
The invention relates to a quick connect coupling (15) for connecting hydraulic lines, especially in earth moving machines and the interchangeable add-on devices and tools thereof. The quick connect coupling (15) comprises a first and a second connecting part (15a or 15b) which can be releasably coupled along a coupling axis to transfer a hydraulic liquid. In order to avoid axial forces during coupling, the hydraulic liquid to be transferred, in the coupled state, emerges from the one connecting part (15a or 15b) at a right angle to the coupling axis and enters the other connecting part (15b or 15a) at a right angle to the coupling axis.
