A filter cloth washing device for a filter press, wherein wash water is sprayed on filter cloths trained about rollers positioned below the filter plates. In the device, wash water supply pipes having a plurality of spraying nozzles run parallel to the rollers, and have coupling means on at least one of their ends. Each coupling means has an inner diameter larger than the inner diameter of its respective water supply pipe, first and second communication ports and flexible pressure hoses for connecting neighboring coupling means to each other. The connection between neighboring coupling means is such that the first communication port of one coupling means is connected by a flexible pressure hose to the first communication port in another coupling means upstream and its second communication port is connected by another flexible pressure hose to the second communication port of yet another coupling means downstream. If the number of filter plates is increased, the water for washing the increased number of filter cloths may be supplied easily and positively by additional pressure hoses of the same length and type.
