A seal (10) including a seal wall (12) comprising a swelling polymer material having elastomeric properties so that the seal has a non-swollen state and an expanded state, the seal wall (12) having a closed circumference that extends around a centrallongitudinal axis (A) and that extends from a first end (12a) via an intermediate section (12c) to a second end (12b) along a length (L) in the direction of the central axis (A), wherein the first end (12a) of the seal sleeve wall is connected or connectable to the inner element (100) and wherein the seal wall (12), apart from at and adjacent to the first end (12a) thereof, is freely radially expandable due to the fact that the second end (12b) and the intermediate section (12c) of the seal wall (12) are not connected to any structural parts. |
