摘要

A device has two clamping bodies, and an elastic sealing body (8) for sealing the device against a wall opening. The body has a pipeline opening for carrying a pipe, where an axial limitation edge of the body is sloped. The body has a surface sloped corresponding to the edge of the body, where material of the body is pressed partially and radially for sealing towards the wall opening, during axial deforming of the body.
