摘要

A retaining sleeve for cleaning brushes (24) in tubular heat exchangers with a cage-like jacket formed by longitudinal webs (12), a stop for the cleaning brushes at one end of the retaining sleeve (10) and a connector (20) at the other end to connect the retaining sleeve with the end of a tube to be cleaned, in which the webs (12) converge pyramidally or domewise at the stop end of the retaining sleeve (10) and are joined together only at the apex (16) of the pyramid.
