ABSTRACT:
A connector part (3) for connecting a material supply device (10) to a spray gun (20) that includes a hollow cylindrical connection piece (5); a threaded wedge element (8) with a lower starting point (8a) and an upper end (8b) running around the outer circumference of connection piece (5) and serving to produce a threaded wedge connection to a counter-element (15) arranged on gun base (19) of spray gun (20); and a stop element (14) that forms a limit stop during the production of the threaded wedge connection. In order to prevent the counter-element on the spray gun from digging into the soft connection pipe made of plastic and removing plastic chips there, it is provided in the connector part according to the invention that stop element (14) is arranged at a distance in the circumferential direction from upper end (8b) of threaded wedge element (8), whereby a gap (11) is formed between stop element (14) and upper end (8b) of the threaded wedge element. In additional embodiments of the invention it is provided that the inclination of threaded wedge element (8) runs more steeply at lower starting point (8a) than in the other area, or that threaded wedge element (8) has a smaller cross section in the axial direction at lower starting point (8a) or at upper end (8b) than in its central area.
