Abstract: The electrode holder for a powder spray gun operable at high voltage includes a powder channel and a web, arranged in the powder channel, for holding a high-voltage electrode. In addition, an annular groove arranged concentrically with the powder channel is provided and is open on the downstream side. A labyrinth for the high voltage is formed by the annular groove together with an annular web of a cap nut, the annular web protruding into the annular groove and said cap nut being used to lock the electrode holder.
