A moisture-absorbing device comprises a plastic tube (1), which is made of flexible plastic sheet and which in its longitudinal direction is divided into an upper chamber containing a moisture-absorbing agent (16) and a liquid-collecting lower chamber communicating with the upper chamber. The plastic tube (1) has an opening on a level with the upper chamber. A netting element (7), which has a netting portion (8), is attached to the plastic tube (1) in such a manner that the netting portion (8) is positioned in front of the opening. The plastic tube (1) is closed at its lower end, thereby enabling collection of liquid in the lower chamber. The moisture-absorbing agent (16) is included in a filtering tube (15), which is made of an air- as well as liquid-permeable filtering material and which is arranged in the upper chamber substantially in front of the opening. |
