The disposable siphon is provided with an outer casing which is sealed in a gastight and liquid-tight manner against a fixed drainage connection piece and is supported against the drainage connection piece at the bottom end. Furthermore, the urinal is provided with an overflow pipe which is directed upwards from the base of the siphon, and with a cover which is equipped with holes for urine to pass through. The cover is connected to an immersion pipe which concentrically surrounds the overflow pipe and generally projects into an oil filling. In the bottom of the disposable siphon, fitting areas for a removal tool are arranged beneath two specially marked urine holes in the cover.
