The invention relates to a fuselage cell structure 1 of an airplane for the simplified installation and attachment of a fastener 15-17,34-37,48 for at least one conduit 18,39-42,49, wherein the fuselage cell structure 1 has a plurality of reinforcing elements 6,8,24,46 that are formed particularly from an aluminum alloy material. According to the invention the reinforcement elements 6,8,24,46 within the fuselage cell structure 1 are provided with at least one groove 12-14,29-33,47, in which the fasteners 15-17,34-37,48 can be fastened by producing a combined pressing and clamping fit creating a positive fit at least in regions. For this purpose, the fasteners 15-17,34-37,46 may have, for example, two retaining feet 19,20 at the base thereof, which can be spread apart and attached by driving a fixing element 21 into the groove 12-14,29-33,47. The reinforcing elements 6,8,24,46 are continuous stringers 3-5 preferably produced by extrusion, and crossbars 23,44,45, wherein the required grooves 12-14,29-33,47 are simultaneously extruded during the production process. In combination with the fuselage cell structure 1, the fasteners 15-17,34-37,48 allow for a flexible, quick, easily exchanged fixation in place of conduits 18,39-42,49 of all types that requires no drilling.
