The invention relates to a device for gassing liquids, particularly waste water, including a gas supply line (1) and at least one gassing element (2), which has a longitudinal axis (L) and can be attached to the gas supply line in a positive manner. In order to simplify the mounting of the gassing element (2), the invention provides that the gassing element (2) has at least one fixing plate (8), which laterally projects relative to the longitudinal axis (L) and which serves to establish a non-positive connection with the gas supply line (1).

The invention claimed is: 1. Liquid gassing device, particularly waste water gassing device, with a gas supply line (1) and at least one gassing element (2), which has a longitudinal axis (L) and can be attached thereto in a form-fit manner, wherein the gassing element (2) has at least one fixing plate (8) projecting laterally relative to the longitudinal axis (L) to establish a force-fit connection with the gas supply line (1), and wherein the gassing element (2) is mounted on the gas supply line (1) with the mounting elements (10) reaching through the fixing plate (8), characterized in that the gassing element (2) made in one piece from a piece of sheet metal has two aerating arms (3), wherein each of the aerating arms (3) is provided with at least one fixing plate (8), wherein the gassing element (2) is formed so that, together with the fixing plates (8), it can be slipped onto the gas supply line (1) in a form-fit manner. 2. Liquid gassing device according to claim 1, wherein the fixing plate (8) is made by bending over a sheet metal portion. 3. Liquid gassing device according to claim 1, wherein the fixing elements (10) are rivets, screw rivets or screws. 4. Liquid gassing device according to claim 1, wherein first breakthroughs (9) are provided in the fixing plate (8) for leading through the fixing elements (10). 5. Liquid gassing device according to claim 4, wherein second breakthroughs (14) are provided in the gas supply line (1) corresponding to the first breakthroughs (9) for leading through the rivets (10) or screw rivets. 6. Liquid gassing device according to claim 1, wherein aerating breakthroughs (7) provided in the gassing element (2) are circular, oval, cornered or slit-shaped. 7. Liquid gassing device according to claim 1, wherein a cross sectional surface running vertical to the longitudinal axis (L) of the gassing element (2) decreases as the distance to the gas supply line (1) increases. 8. Liquid gassing device according to claim 6, wherein an opening surface of the aerating breakthroughs (7) provided in the gassing element (2) increases from top to bottom. 9. Method of mounting the liquid gassing device according to claim 1 consisting of the following steps: slipping the gassing element (2) onto the gas supply line (1), so that the fixing plates (8) are positioned next to the gas supply line (1) in a form-fit manner, and mounting the gassing element (2) on the gas supply line (1) with the mounting elements (10) reaching through the mounting plates (8). 10. Method according to claim 9, wherein rivets, screw rivets or screws are used as mounting elements (10).
