A system for passing a cable, a conduit, a pipe or the like sealingly through an opening in a wall, comprising a sealing device made of an elastic material, such as rubber, which includes at least one lead-through channel having a smooth inner wall, wherein the sealing device is externally provided with axially spaced-apart, circular, at least substantially inflexible, compressible ribs lying in (imaginary) radial planes, whose outside diameter is larger than the inside diameter of the opening, and wherein the system furthermore includes at least one grommet to be fitted round the cable, the conduit, the pipe or the like that is to be passed through, which grommet can be fitted sealingly in said lead-through channel, which grommet, which has a smooth outer side, includes a bore whose wall is provided with axially spaced-apart, circular, at least substantially inflexible, compressible ribs lying in (imaginary) radial planes, whose inside diameter is at least substantially identical to the outside diameter of the cable, the conduit, the pipe or the like that is to be passed through. |
