These known arrangements of the steel pipe cannot take place in the production site which does not provide the pipes for sealing large underground lines, but must have been determined and thus be carried out on the spot for these special ones. The ^{difficulties encountered in the masonry 6} S cases of application were quite costly and the tight fitting could not be precisely controlled for the present application of the bitumen. Purpose cannot give any indication, as in the rest of F-isL-hwercnd it is added that with this arrangement also the age of these references clearly shows.

An embodiment of the invention is shown below explained on the basis of the drawing. The drawing in

Fig. 1 is an exploded view of the arrangement according to the invention in a non-scale representation and in

2 shows a section through the inventive Cuff according to line 2-2 in FIG. 1.

In Fig. I is the product pipe with 1, with 2 a Protective tube and designated with 3 a protective cable tube. The product pipe lies within the protective pipe 2 and is supported by spacers 4, which are known per se and are made of plastic, with individual segments of these spacers 4 being connectable to one another to form a ring. Due to the formation of the spacers 4, the product pipe 1 lies on the lower inner surface of the Protective tube 2, eccentrically within the protective tube 2.

Finer of the hook segments 4 carries a holder for the protective cable pipe 2, which is parallel to the product pipe 1 is performed.

The open side of the protective tube 2 \ v, rd is closed by a sleeve 5, which essentially consists of an end face 6 in which, in adaptation to the eccentric position of the product tube 1, a passage opening? and in adaptation to the position of the cable protection tube 3, a further passage opening 8 is provided. Both passage openings 7 and 8 are surrounded by collar-like annular flanges 9 and 10, which are designed to protrude towards the free end face 6, as shown particularly clearly in FIG. 2 shows.

On the back of the cuff a further collar-like ring flange 11 is provided, which is on the outside of the protective tube 2 can lay and is preferably designed to widen somewhat conically, while the annular flanges 9 and 10 are somewhat are designed conically narrowing towards their free mouth. This achieves the required contact pressure on the product pipe 1 and on the protective cable pipe 3, and on the other hand, the sleeve can be easily pushed onto the outside of the Protective tube 2 guaranteed.

The determination of the annular flanges 9, 10 and 11 to their associated tubes, can take place via belonging to the prior art, preferably made of non-corrosive material bandages so that in this way a rapid dismantling of the entire sleeve is possible.
