Nozzle body acting as an insoluble anode for the galvanic or chemical treatment of rod-shaped or pipe-shaped objects continuously moved through the nozzle body and acting as cathode. The nozzle body is arranged in a hollow body serving as a pressure vessel, the electrolyte flowing through the hollow body. The hollow body has a plurality of radial bore holes (44) acting as nozzles, these bore holes (44) being arranged in a plurality of cross-sectional regions (11) lying at a distance from one another and being inclined at angles (.alpha.) and (.beta.) relative to the longitudinal axis (16) of the nozzle body (34) and relative to the respective crosssectional region (11). Diaphragms (36) are associated with the nozzle body (34) which is coated on all sides with a layer of metal from the platinum group. The diaphragms (36) are arranged in the through-opening (35) of the nozzle body (34), surround the body (15) to be treated, and are situated in planes (A, B, C, D and E) between the outlet openings of the bore holes (44). The through-flow openings (37) of the diaphragms (36) are enlarged in cross section in a stepwise manner in the direction opposite to the throughput direction (5) of the body (15) for the purpose of preventing a pressure drop in the nozzle body (34).
