The invention relates to a coupling arrangement (12, 14, 82, 84, 152, 156) for a screw coupling (10, 80, 150) for liquid lines of a high-pressure cleaning device. The coupling arrangement (12, 14, 82, 84, 152, 156) has a plug part (16, 48, 86, 106, 154, 158), which can be connected to a complementarily designed plug part of a second coupling arrangement of the screw coupling (10, 80, 150) in a pluggable manner in order to produce a liquid-tight and releasable connection with the interposition of a sealing ring (28, 90, 162), and a connecting part (38, 51, 92, 124, 164, 192) with a thread (50, 52, 96, 132, 168, 196), which can be screwed together with a complementarily designed thread of the second coupling arrangement. In order to allow the coupling arrangement (12, 14, 82, 84, 152, 156) to be quickly connected to the second coupling arrangement in a liquid-tight manner while ensuring that the connection is not accidentally released, the thread (50, 52, 96, 132, 168, 196) is designed as a multiple thread, and the connecting part (38, 51, 92, 124, 164, 192) has a clamping element (56, 60, 100, 128, 172, 200) which is aligned with the thread (50, 52, 96, 132, 168, 196) with respect to the thread longitudinal axis (63, 134, 202) and which can be clamped with a complementarily designed clamping element of the second coupling arrangement in a releasable manner by axially guiding one into the other. |
