ο the like. to lead. With sensitive plastic coating ^ this danger is particularly great. With such plastic-coated Ears also run the risk of damaging the inner edge of the boring insert end and the Is exposed to corrosion. Another disadvantage of the known push-in socket connections is that through the ruffling of the inner edge of the tube spigot end The Sehall transmission is very promoted at the socket base. It therefore provides the known plug-in socket connections Sound bridges that are highly undesirable during installation. Finally, offer the push-in socket connections of the known type no protection against the transmission of any static electrical charges, rather there is generally a conductive connection between the line sections to be connected.

The utility model is based on the object, through a further embodiment of the plug-in socket connection of the Type specified at the beginning, the risk of damage to the socket base or the inner edge of the pipe plug-in end to eliminate and at the same time prevent the formation of sound bridges. This is done according to the utility model achieved in that between the inner socket wall-ung and an annular, sound-insulating body is interposed between the pipe insertion end whose lower, inwardly protruding edge is the inner edge of the pipe plug-in end and that rests on the socket base supports. This insulating body thus prevents direct contact with the inner edge of the tube plug-in end with the socket base and thus the risk of damage. On the other hand, this insulating body offers a Sound insulation between the pipe insertion end and the socket, so that Sehall bridges can be avoided. The assembly the insulating body is extremely simple. The insulating body can be connected to one of the Parts fastened and assembled with it to form a socket connection or it is inserted separately.

MATERIALS ARE IMPORTANT.

According to another embodiment of the utility model the insulating body is designed in the shape of a sleeve and rests against the inner wall of the sleeve. Through this a particularly elongated insulation and a secure holding of the insulating body in the sleeve is achieved. Furthermore, a very simple assembly is possible by inserting the sleeve-shaped insulating body into the sleeve up to its support on the socket base and then the pipe plug-in end is inserted.

IHir a push-in socket connection where between the socket edge and the pipe plug-in end a pressure-secured sealing sleeve is arranged, it is special expedient if in further training of the utility model of the mansohette-shaped insulating body from Socket base up to the inner edge of the sealing collar enough. As a result, the entire space not taken up by the sealing sleeve is covered by the insulating body, what also for the complete electrical insulation against e.g. leakage currents from Yorteil.

About a peat production and as simple as possible To enable assembly, according to a further embodiment of the utility model of the insulating body in the The sleeve must be glued in place.

In the drawing is an embodiment of the utility model shown, in the form of a longitudinal section.

- The socket connection shown for Installation lines consist of a pipe receiving end 1 widened to form a socket and an associated pipe plugging end 2 and a closed sealing cuff 3, which is between the sleeve edge, which is deformed into a bead 4 and the tube insertion end 2 is interposed.

Between the inner wall of the sleeve 1 and the pipe plug-in end 2 is a ring-shaped, against sound insulating body 5 interposed, on its lower, inwardly protruding edge 6, the inner edge 7 of the pipe plug-in end 2 rests and which itself on the socket base! 8 supportsi

The insulating body 5 with its edge 6 also consists of electrically insulating material. The insulating body is designed in the shape of a sleeve and rests against the inner wall of the sleeve. In the illustrated embodiment with the sealing collar 3, it extends from the socket base 8 to the inner edge of the sealing collar 3, as the drawing shows. The sleeve-shaped insulating body 5 can be glued into the sleeve 1.

As the drawing clearly shows, the inner edge 7 of the tube plug-in end 2 is always supported over the edge of the insulating body 5 on the socket base, so that no direct contact between the edge 7 of the pipe steek end 2 and the socket base 8 can take place, whereby Damage, sound bridges and electrical conduction are excluded.
