In the perspective view of FIG. 1, the radiator flange 21 or respectively the flange plate 25 is shown at a distance from the radiator attachment 1, therefore before mounting of the radiator attachment 1 on the radiator flange 21 or respectively on the flange plate 25. The radiator attachment 1 engages through the through-opening 22 provided on the radiator flange 21 and is fixed detachably on the radiator flange 21.

[0036] The assembly of the radiator attachment 1 can takes place as shown in FIGS. 4a and 4b.

[0037] Accordingly, the socket lower part 8b, 8, the sleeve body 10 and the socket upper part 8, 8a are pushed along the axial direction A successively onto the sleeve body 10 (cf. arrows P1 in FIG. 4a), wherein the collar 9 projecting from the sleeve body 10 functions as an axial stop. Thereafter, as shown in FIG. 4b, the spreading element 3, projecting from the tank bottom 2, is pushed into the resulting structural unit 17 along the axial direction A into the body interior 5, delimited by the detent body 4, (cf. arrow P2 in FIG. 4b), until the two spreading hooks 16a, 16b are engaged with the two inner detent elements 6a, 6b, projecting from the detent body 4 into the body interior 5.

[0038] FIG. 5 illustrates in a perspective sectional view an example of a radiator attachment according to the invention in accordance with the second aspect of the invention. Here, in contrast to the example of FIGS. 1 to 3, the sleeve body 10 is dispensed with. Furthermore, in this variant, contrary to the example of FIGS. 1 to 3, two flange tongues 24a, 24b project axially from the opening edge 23 of the vehicle flange surrounding the through-opening 22. Each of the two clip elements 12a, 12b of the socket 8 is engaged or clipped with an opening edge 23 of the radiator flange 21 surrounding the through-opening 22.
