Abstract
The invention provides a liquid spray gun connectable to a fluid reservoir through a fluid outlet. The spray gun comprises a socket geometry arranged for engagement with a co-operating connector for releasable connecting the spray gun with the fluid outlet. The socket geometry comprises a bore having an opening on one end, an end surface surrounding the bore's opening at least partially, and a lug portion spaced apart from the end surface in an axial direction parallel to a central axis of the bore. The lug portion has a lower surface being adapted to engage with the connector and to retain the connector in the axial direction. The end surface comprises a first keying geometry that is adapted to restrict rotation of the connector in at least one direction.
