A paint spraying gun with a gun body and a material supply device that are connected to one another by a screw-wedge connection. The screw-wedge connection includes a screw-wedge element that is arranged on the circumference of an essentially hollow-cylindrical connecting part of the material supply device, and a corresponding counter element on the gun body. The connection is inexpensively manufactured and easily handled. The screw-wedge element extends in an arc over more than half of the circumference of the connecting part with the ends of the screw-wedge element being peripherally spaced from one another. The counter element is an arcuate projection arranged on one side of and above a receiving bore of the gun body.
