A method of replacing damaged parts of wastewater channels with inserted parts, e.g. optical cables, includes removing a section of the channel, positioning a lower half-shell (1) below the inserted part (2) at the remove d section of the channel, passing an attachment element (3) having two ends (3 a, 3b) around the inserted part (2), feeding the attachment element (3) through at least one opening (4, 6) of an upper half shell (5), placing the upper half shell (5) on the lower half shell (1), attaching the upper half shell (5) to the lower half shell (1), attaching the upper and lower half shells (5, 1) to neighboring channel sections, pulling the ends of the attachment element (3) tight to press the inserted part (2) against the inner surface of the channel, and filling the opening (4, 6) with a sealing compound (7).
