Filler bodies for the biological purification of, for example, waste water are fitted together from individual filler-body blocks. In this case, these have to be releaseably connected to one another. In known filler bodies, adapters are used for this purpose which obstruct the ability of the waste water to flow through or around the filler body. As a result, the cleaning capacity is also reduced. The filler body according to the invention has at least one tube of one or each filler-body block (21, 22, 23, 36, 40, 45) as a tube (31, 37, 38, 39, 56) which extends over a plurality of filler-body blocks (21, 22, 23, 36, 40, 45). As a result, the individual filler-body blocks (21, 22, 23, 36, 40, 45) are connected to one another in a positive-locking manner without the ability to flow through or around the filler body being obstructed. The filler body according to the invention is particularly suitable as a substrate for a so-called biological lawn for the biological purification of waste water or gases.
