Abstract
A line penetration for routing a line through a building part. The line penetration includes a first lamellar element with a hollow-cylindrical first base part for receiving the line in a straight-through line opening, and with first circumferential lamellas, which extend outwardly transverse to an axial direction of the first base part; a second lamellar element with a hollow-cylindrical second base part for arrangement in a passage opening of the building part, and with second circumferential lamellas, which extend inwardly transverse to an axial direction of the line opening, where the first and second lamellas mesh with one another in the manner of a comb, so that the side faces of the lamellas are impermeable to gas and bear slidingly on one another.
