The head has a flanged socket (4) at a part (1), where a sprinkler hole is formed at another part (2). The parts are connected along ring-shaped edge sections (3, 6), where the parts are fluid tight connected with each other. The parts are made of ultrasonic-weldable plastic, polypropylene and polyethylene. The sections of the parts are formed as a plane surface and laid parallel to each other and ultrasonically welded together. A cylindrical projection (7) is projected in a perpendicular manner. A border region is turned in one of the sections of one of the parts in an assembled condition. An independent claim is also included for a method for manufacturing a plastic watering can sprinkler head.
