    In Fig. 1, the fuel tank of a truck is summarily denoted by 1. Whose wall 2 has a curvature region 3 with the axis of curvature 3 ', in which at an only indicated opening 4 an inventive filler neck 5 is attached. However, such could also be arranged in the planar region of the wall 2. The wall consists of sheet metal, preferably a thin sheet of light metal, the parts of the filler neck 5 are made of a suitable plastic, for example, sprayed.
    The filler neck consists of two parts. In Fig. 2 of the wall 3 with respect to the outer nozzle part is denoted by 8 and the inner nozzle part 9. For correct angular positioning of the filler neck 5, the opening 4 has a recess 6. The nozzle parts are tubes in their basic form. The outer neck part 8 is surrounded by an outer collar 10 and the inner neck part 9 by an inner collar 11. According to the curvature of the wall 3, the collars have a spatial shape, so that they rest on the outside or inside of the wall sealing. The outer neck part 8 has an outer edge 12, which is provided with means for attaching a cover, not shown here, bayonet ramps 13, 4 ', 4', 4 ', 4' ', 4' ' , is provided. The tank inner edge is formed by the outer collar 10, the first bearing surface 17 (see FIG. 3) rests against the wall 3. On the inside of the outer neck part 8 is at the same height over the circumference distributed a number (six here) formed by longitudinal grooves 15 in which inwardly projecting shoulders 16 are formed.
    The inner nozzle part 9 is in its basic form also a tube whose tank inner edge 19 is for reasons of strength in an axially normal plane and which is surrounded by an inner collar 11. This (11) abuts with a second contact surface 24 on the tank inner side of the wall 3. At the outer edge of the inner nozzle part 9, a corresponding number of elastic tongues 20 is formed, the snap hooks 21 engage over the shoulders 16 of the outer nozzle part 8 and so firmly hold the two nozzle parts, as shown in Fig. 3. The tongues 20 fit into the longitudinal grooves 15, whereby the inner neck part 9 and the outer neck part 8 are positioned at right angles to each other. Means for gripping the inner nozzle part 9 are designated 25.
    In Fig. 3 the assembled filler neck can be seen. It can be seen that the inner neck part 9 is double-walled. On its outer wall connects via a lying in an axis normal plane circular ring 22 a tankeinwärts directed inner tube 23 at. The outer diameter of the inner neck part 9 is equal to the inner diameter of the outer neck part 8 whereby they are centered to each other. The inner collar 11 forms a second bearing surface 24, which follows the curvature of the wall 3.
    In Fig. 4a, the snap connection between the outer (8) and inner nozzle part 9 is shown enlarged. The outer nozzle part 8 has on its inside for each snap hook 20 an upwardly-inwardly rising ramp 30 which terminates in a tank-facing axially normal shoulder 16. During assembly, the snap hook 21 rides on the ramp 30. Through this (30), the tongue 20 is bent radially inwardly during assembly until the snap hook 21 engages over the shoulder 16.
    In the variant of FIG. 4b, a ramp 30 'is formed on the snap hook 21', which slides on the inner lower edge 26 'and the tongue 20' bends radially inward until the snap hook 21 'engages over the shoulder 16'.
    The second embodiment differs from the first in that the spring tongues are not arranged on the inner neck part 9, but on the outer neck part 8. In Fig. 5 and Fig. 6 (the wall 3 is omitted in Fig. 6) is arranged on the tank inner edge 52 of the outer nozzle part 8 in extension of the nozzle wall, a number of elastic tongues 50 distributed over the circumference. The tongues 50 have radially inwardly directed snap hooks 51, which latch onto the inner support part as described with reference to FIG. 7.
    In Fig. 7, the section is parallel to the axis of curvature 3 '(Fig.l) out, which is why the collar 10, 11 seem to lie in a achsnorma-len plane. The inner nozzle part 9 is double-walled. An outer tube 60 extends from the second collar 11 inwardly of the tank and at its lower edge via an annular ring 61 (see Fig. 8) in an inner tube 62 via. As a result, a gap 63 is formed between outer tube 60 and inner tube 62 all around (see FIG. 8). In this dip the tank inner continuation 8 'of the outer nozzle part 8 and its elastic tongues 50 a. Their snap hooks 51 engage under shoulders 57 of the openings 56 distributed over the circumference. The width 64 of the snap hook 51 (see Fig. 6) is gi oak the width 64 of the apertures, whereby the two nozzle parts 8, 9 are positioned in the direction of rotation to each other.
    In FIG. 8, the section is guided in a normal plane to the axis of curvature 3 '(FIG. 1), so that it can be seen that the two collars 10, 11 are adapted to the curvature of the wall 3. The outer nozzle part immersed in the annular space 63 between the outer tube 60 and inner tube 62 a. When the outer diameter of the inner tube 62 is equal to the inner diameter of the outer nozzle part 8, the two nozzle parts 8, 9 are centered relative to one another. On the right side of Fig. 8 is further a nose 66 of the outer neck part 8 can be seen, which fits into the recess 6 in the contour of the opening 4, whereby the neck is positioned at right angles to the opening 4. * *
