The invention relates to a device for leading a supply line through a masonry structure. The device exhibits first of all a protective tube, which can be inserted into a masonry-structure bore of predetermined diameter, and a device for supporting the protective tube on the supply line. The space between protective tube and masonry-structure bore can be filled by a sealant. The protective tube is provided with a guide ring which is arranged at a distance from the outer end of said tube and by means of which the protective tube can be guided in the masonry-structure bore. A filling tube passes through the guide ring, which tube is arranged in the annular space between protective tube and masonry-structure bore and, in the region of the inner end of the protective tube, can be connected to a sealant pump. The sealant is pressed, under superatmospheric pressure, via the filling tube into the space which is directed towards the outside of the masonry structure and is located in front of the guide ring. Outside, in front of the masonry structure, the sealant thus forms a sealing plug which is widened in diameter, effects secure sealing and ensures that gas which is released even outside in front of the masonry-structure lead-through point, or liquid which is released or is located there, does not penetrate via the masonry-structure bore into the masonry structure and into the building of which the masonry structure forms a part. <IMAGE>
