Abstract
A coupling arrangement for a screw coupling for liquid conduits of a high-pressure cleaning apparatus is provided. The coupling arrangement includes a plug part which is pluggably connectable to a complementarily configured plug part of a second coupling arrangement of the screw coupling for establishing a liquid-tight and releasable connection therewith with a sealing ring interposed therebetween, and a connecting part having a thread that is screwably connectable to a complementarily configured thread of the second coupling arrangement. The thread can be of multiple-threaded configuration and the connecting part can include a clamping element which is aligned in an in-line relationship with the thread relative to the thread longitudinal axis and is releasably clampable against a complementarily configured clamping element of the second coupling arrangement by axially inserting one into the other.
