Fig. 5 shows a longitudinal member 100 as part of the frame of a chassis of a vehicle, which is only partially shown. The carrier 100 includes a vertical web 102 and a horizontal top flange 104 on the web 102, which extends perpendicular to the vertical web 102 inwardly of the vehicle. The holder 10 is mounted below the upper flange 104 on a vehicle interior of the vertical web 102, its mounting flange area 14 being fastened to the vertical web 102. As a fastener, a screw 106 is inserted through a mounting hole 18 (see FIG. 1) of the mounting flange portion 14 and also through an installation hole that extends through the vertical web 102. As can be seen in FIG. 5, a plurality of installation holes 108 are arranged in the vertical web 102 in a matrix. It is possible to select a different installation hole 108 from the number of installation holes shown in FIG. 5 for mounting the holder 10 in an alternative position. A screw 106 and a nut are required for assembly.

In the mounting position shown in Fig. 5, the flat mounting area 12 extends horizontally in the longitudinal direction A-A corresponding to the longitudinal direction of the longitudinal beam 100 and further corresponding to the extension direction of the supply lines 110 to be installed on the longitudinal beam 100. The flat storage area 12 lies below the lower surface of the upper flange 104, with the flexible supply lines 110 attached to the lower surface of the storage area 12. These flexible supply lines 110 are attached to the flat storage area 12 by means of straps 112 as fastening means for attaching the flexible supply lines 110 side by side to the lower surface of the storage area 12. Each of the straps 112, 114 is designed as a closed loop for running around the storage area 12 and the flexible supply lines 110 and is received in the notches 28, 30, 32, 34 on the edges of the storage area 12 in order to hold the position in the longitudinal direction A-A. In detail, a first band 112 surrounds the first extension area 24 of the bearing area 12 so that it rests in the notches 28, 30, while a second band 114 surrounds the second extension area 26 and is received within the notches 32 and 34. The straps 112, 114 hold the flexible supply lines 110 on the underside of the flat storage areas 12 next to one another without the risk of damage. On the other hand, any loosening of the fastening of the flexible supply lines 110 is prevented, and the flexible supply lines 110 are fastened in their positions parallel to one another.

In the mounting position in Fig. 5, the wing portions 36, 38 are angled in an upward direction so that the front and rear edges of the wing portions 36, 38 are kept away from the flexible supply lines 110 to prevent any damage.

The additional bearing flange 20 extends further from the vertical web 102 over the outer edge of the horizontal upper flange 104 away. The assembly hole 22 at the end of the additional bearing flange 20 is used to assemble a clamping piece 116 for clamping an additional rigid supply line 118 at a distance parallel to the remaining supply lines 110 which are supported by the bearing area 12. Since the clamping piece 116 is mounted on top of the additional bearing flange 20, the additional rigid supply line 118 is mounted at a higher level than the remaining supply lines 110. For example, this additional supply line 118 is a rigid hydraulic steel line, while the remaining flexible supply lines 110 are pneumatic hoses , Fuel hoses, electrical cables or the like.

Due to the rigidity of the supply line 118, the holder 10 cannot be rotated about the axis of the screw 106, and thus the installation of the holder 10 on the side member 100 is torque-proof.
