Abstract
The invention relates to a hollow body, in particular a pipe segment or a cylindrical body which contains gases or fluids or through which these can flow and comprises at least one opening in its wall surrounding the hollow space of the hollow body, the opening entering into a ring groove in the hollow body wall which extends around the entire outer periphery of the hollow body and over which opening a filter mesh strip located in this ring groove is spanned. In both side wall of this ring groove there are provided essentially opposing slot-shaped recesses extending annularly with the groove. The filter mesh strip is inserted into these recesses and held there by both its side edges.
