A sealing element for use for introducing a pipeline through a hole in a well consists of an essentially bushing-shaped part 12 made of an elastic material and a rigid, bushing-shaped member 13 which is preferably made of plastic material. The rigid, bushing-shaped member 13 is adapted so as, when the sealing element is fastened, to be driven into the bushing-shaped part 12 so that the latter is clamped tightly against the sides of the hole. Positioned at the opposite end of the bushing-shaped part 12 in relation to the insertion end of the rigid, bushing- shaped member 13 is a flexible connecting piece 16 which narrows stepwise and which is arranged so as to bear sealingly against the outer side of the pipe which is to be guided through the wall. In the connection, use is made of the step which fits the pipe in question, and the connecting piece is fastened preferably by means of a hose clamp around the pipe. Such a sealing element brings about reliable sealing against both seeping in and seeping out of water from the assembly, to which the line is connected. <IMAGE> |
