Disclosed is a holder for fixing all types of component, in particular lines, without using holes and largely without using tools inside a conventional fuselage structure of an aircraft with stringers and annular formers, the formers each being provided with an angle bracket at crossing points between a stringer and an annular former. The holder is configured so as to be split in two with a lower part and an upper part which can be connected thereto, the lower part being slidable onto an angle bracket. By attaching the upper part to the lower part, the holder is positionally fixed at the crossing point in the top region of an annular former. It is fixed in its final position by connecting the holder to a transverse line holder as a function element by means of an expansion pin or other connection elements. Other alternative function elements for fixing the components, such as a longitudinal line holder, a transverse batten or a longitudinal batten for specific installation requirements, may, if necessary, be combined with at least one holder so as to form holder arrangement with any desired degree of complexity.
