## Abstract

A sealing tape for wrapping up a cable, in particular a communication cable or the like, to be extended through a cable passageway opening, for forming a seal between the cable and the cable passageway opening, has on its inner surface facing the cable a roughened surface area that excludes axial and circumferential displacement of the sealing tape relative to the cable under influence of intervening axial and torsional loads, thereby insuring anti-skid placing of the cable in the cable passageway opening.

## Claims

### Claim 1

A sealing tape for wrapping up a cable to be extended through a cable passageway opening to form a seal between the cable and the cable passageway opening, said sealing tape comprising an inner surface facing the cable and having a roughened surface area, said roughened surface area being formed by friction elements protruding from said inner surface, and said friction elements being made as friction teeth which are made of a metal and are anchored in a sealing tape material, wherein said friction teeth are squeezed out from a sheet metal insert, and wherein said sheet metal insert includes openings and sheet metal panels encompassing said openings, said friction teeth protruding from said sheet metal panels, and said sheet metal panels having portions free of friction teeth and land portions extending from said free portions between adjacent openings.

### Claim 2 (depends on 1)

A sealing tape as set forth in claim 1, wherein said openings and said sheet metal panels are arranged in rows transverse to a lengthwise direction of said sealing tape, said sealing tape further comprising sheet metal strips separated by said openings and extending in the lengthwise direction of said sealing tape for connecting said sheet metal panels, said sheet metal strips being formed by said land portions which extend transverse to the lengthwise direction of said sealing tape.
