The invention relates to a substantially fire resisting seal device for a through hole in a partition for conducting one or more cables there through. The device comprises a substantially annular sawing sleeve. Said sleeve defines an inner passage for conducting at least one cable there through. It is noted that the sleeve is provided with saw teeth positioned at a distal end portion of said sleeve. Further, the seal device comprises an insertion plug for enclosing a portion of one or more cables conducted through the sawing sleeve. The device is arranged such that the insertion plug can be inserted into the sawing sleeve at least partly such as to substantially seal off the passage through the sawing sleeve. Advantageously, the insertion plug may comprise a compressible seal material, e.g. a compressible foam, preferably a resilient foam, for enclosing a portion of one or multiple cables. |
