The gun has an inlet in the handle for compressed air. The air is led into it through a pipe connecting an air compressor to the handle through a venturi. The venturi provides a secondary ambient air inlet. A connector (8), upstream of the venturi, has a slide (9) displacing between first and second positions, to respectively prevent or allow the supply of compressed air. A central cap (13) separates upstream (12) and downstream (11) parts. A radial orifice (14,15), from each side of the cap, links the inside and the outside of the connector. The external surface (16) of the connector is cylindrical, having a slide around the connector with two internal annular grooves (19,20). Each groove has a toroidal joint (22,21) sealing the external and internal surfaces of the connector.
