The water drain arrangement includes a drain channel, a tubular feed-through device extending through a first opening of a first wall panel of the body and a second opening of a second wall panel of the body. The water drain arrangement includes a body shell-fixed sleeve extending through the first shell opening of the first wall panel and is coupled to the first wall panel in a fluid-tight manner. A first end of the feed-through device is inserted through a first end of the body shell-fixed sleeve and includes a drain extending through a second end of the feed-through device. A free end of the drain channel is held in a fluid-tight manner in a seat of the feed-through device, which is disposed at a second end of the feed-through device. ## Claims ### Claim at position 1 -10. (canceled) ### Claim 11 A water drain arrangement for a body of a vehicle, comprising: a drain channel; a tubular-shaped feed-through device extending through a first body shell opening of a first wall panel of the body and a second body shell opening of a second wall panel of the body; and a body shell-fixed sleeve extending through the first body shell opening of the first wall panel of the body and coupled to the first wall panel of the body in a fluid-tight manner, wherein a first end of the feed-through device is received through a first end of the body shell-fixed sleeve, and the first end of the feed-through device comprises a drain extending through a second end of the feed-through device, wherein a second end of the feed-through device comprises a seat receiving a free end of the drain channel, and the free end of the drain channel is held in a fluid-tight manner against the seat of the feed-through device, wherein the body shell-fixed sleeve includes a first sealing collar connected to the first wall panel of the body of the vehicle and covers the first body shell opening to seal the connection between the first wall panel of the body and the body shell-fixed sleeve, and wherein the seat of the feed-through device includes a second sealing collar engaging the second wall panel of the body of the vehicle and covers the second body shell opening the second wall panel of the body in a sealing manner. ### Claim 12 (depends on 11) The water drain arrangement according to claim 11, further comprising: a first sealing element arranged between the first sealing collar and the first wall panel. ### Claim 13 (depends on 11) The water drain arrangement according to claim 11, further comprising: an anti-retraction device disposed on an outer wall of the drain, wherein the anti-rotation device is configured to be set in a mounted state such that the anti-rotation device engages the first sealing collar of the body shell-fixed sleeve. ### Claim 14 (depends on 11) The water drain arrangement according to claim 11, further comprising: a first seal disposed on the feed-through device between the seat and the drain, wherein the first seal engages an interior surface of the body shell-fixed sleeve to define a sealed interface between the interior surface of the body shell-fixed sleeve and the exterior surface of the feed-through device. ### Claim 15 (depends on 11) The water drain arrangement according to claim 11, wherein an end of the seat of the feed-through device comprises an insertion funnel. ### Claim 16 (depends on 11) The water drain arrangement according to claim 11, wherein an inner wall of the seat includes a stop defining an insertion depth of the drain channel received in the seat of the feed-through device. ### Claim 17 (depends on 11) The water drain arrangement according to claim 11, further comprising: a second seal disposed on an exterior surface of the free end of the drain channel, wherein the second seal engages an inner wall of the seat to define a sealed interface between the inner wall of the seat and the exterior surface of the free end of the drain channel. ### Claim 18 (depends on 17) The water drain arrangement according to claim 17, wherein the second seal comprises one or more rubber-elastic sealing lips. ### Claim 19 (depends on 14) The water drain arrangement according to claim 14, wherein the first seal comprises one or more rubber-elastic sealing lips.
