2. DESCRIPTION OF THE RELATED ART
German Patent No. DE-GM 86 22 603.7 discloses a heatable hose in which a heater is arranged in the hose wall parallel to its interior. The interior is offset unilaterally from the hose axis so that one side of the hose has a thickened cross section in which the heater is embedded. The hose wall region between the interior and the heater has a thinner cross section than the hose wall region between the heater and the adjacent surface of the hose.

5. DETAIL~D DESCRIPTION OF~THE PREF~RRED EMBODIMENTS
Referring to Figure 1, there is shown a longitudinal sectional view of a connecting member 1 for the longitudinal connection of two hoses 2 and 2a. Connecting member 1 includes a connecting body 3 surrounded by an encasing tube lo composed of two half shells of which only the lower half shell 12 is visible in Figure 1. Hoses 2 and 2a have free end~ 4 and 4a, respectively, which are inserted into half shell 12 after previously having been connected with one another by way of connecting body 3 which has partial end regions 5 and 5a inserted into the interior of hoses 2 and 2a at the free ends 4 and 4a, respectively of the hoses. Around their circumference, partial end regions 5 and 5a of connect-ing body 3 are each equipped with regions 31 and 32 of graduated thickness, with the thickness increasing in the insertion direction (i.e. the direction in which the tube is pushed over the connecting body) so as to prevent the easy removal of the hose ends from connecting body 3. Pressure webs 123 and 124 are formed within half shell 12 in a region adjacent each of its free ends 6 and 6a, respectively, which effect an operative clamping connection with the portions of , ... . .

graduated thickness of connecting body 3 when the hoses 2 and 2a are connected by connecting body 3 and inserted into half shell 12. That is, pressure webs 123 and 124 cause the flexible hose sections disposed about the inserted partial 5 end regions 5 and 5a of connecting member 3 to be addition- -ally pressed against the regions 31 and 32 of graduated thickness. In this way, the hose ends are fixed to the inserted partial end regions 5 and 5a of connecting member 3 in an almost unreleasable manner.
As an additional safety, the end regions of each half shell are configured as annular clamps 125 and 126, converging radially inwardly toward the respective free ends
Referring to Figure 1, there is shown a longitudinal sectional view of a connecting member 1 for the longitudinal connection of two hoses 2 and 2a. Connecting member 1 includes a connecting body 3 surrounded by an encasing tube lo composed of two half shells of which only the lower half shell 12 is visible in Figure 1. Hoses 2 and 2a have free end~ 4 and 4a, respectively, which are inserted into half shell 12 after previously having been connected with one another by way of connecting body 3 which has partial end regions 5 and 5a inserted into the interior of hoses 2 and 2a at the free ends 4 and 4a, respectively of the hoses.

That is, pressure webs 123 and 124 cause the flexible hose sections disposed about the inserted partial 5 end regions 5 and 5a of connecting member 3 to be addition- -ally pressed against the regions 31 and 32 of graduated thickness. In this way, the hose ends are fixed to the inserted partial end regions 5 and 5a of connecting member 3 in an almost unreleasable manner.

Before the two half shells are connected, a flowable insulating substance, which may be any one of a number of commercially available foamable insulation materials, may be introduced into the interior space of the half shells so as to completely fill the interior space remaining between the half shells and the hose connection combination. The annular clamps 125 and 126 at the end regions of the half shells prevent the insulating material from flowing out.

Such foamable insulation materials include, for example, the flowing polyurethane compound "Elastroform IDA
4056 - 24 manufactured by Wacker Chemie, West Germany, or the flowing silicone compound "Elastosil E 41" also manufactured by Wacker Chemie, West Germany. The annular clamps 125 and 126 at the end regions of the half shells prevent the insulating material from flowing out. It is also possible to introduce the insulating material into the interior space formed by the connection of the two half shells through an appropriate fill opening (not shown) at a later time. The material may be a foamable insulating material whichr after foaming, fills the interior space in both a sealing and insulating manner.
The ends of hoses 2 and 2a are prepared such that heating wires 23 and 24, respectively, are exposed. Before assembly of the two half shells, the electrical connection between heating wires 23 and 24 must be established, generally by way of a solder connection 231.
The upper half shell which is not shown in Figure 1 is a mirror image of lower half shell 12, and is joined to lower half shell 12 by means of connecting means 121 and 122.

Such foamable insulation materials include, for example, the flowing polyurethane compound "Elastroform IDA
4056 - 24 manufactured by Wacker Chemie, West Germany, or the flowing silicone compound "Elastosil E 41" also manufactured by Wacker Chemie, West Germany. The annular clamps 125 and 126 at the end regions of the half shells prevent the insulating material from flowing out. It is also possible to introduce the insulating material into the interior space formed by the connection of the two half shells through an appropriate fill opening (not shown) at a later time. The material may be a foamable insulating material whichr after foaming, fills the interior space in both a sealing and insulating manner.
The ends of hoses 2 and 2a are prepared such that heating wires 23 and 24, respectively, are exposed. Before assembly of the two half shells, the electrical connection between heating wires 23 and 24 must be established, generally by way of a solder connection 231.
The upper half shell which is not shown in Figure 1 is a mirror image of lower half shell 12, and is joined to lower half shell 12 by means of connecting means 121 and 122.
