The cable bushing has a covering body (11) and a sealing body (10), where micro ducts or mini ducts (13) are inserted in an inner space of the cable bushing over a common cable guide (12) and are radially enclosed from outside by a common casing (14). A funnel-shaped element (16) is positioned between the casing and the cable guide. A sealing element (15) of the cable guide is sealed against the funnel-shaped element. A hardened sealing material is inserted between the funnel-shaped element and the casing for sealing the funnel-shaped element against the casing.
