   In den Fig. 1 und 2 der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. 



  Es zeigen Fig. 1 teilweise im Schnitt das Rohr und Fig. 2 einen Teil-Längsschnitt des Rohres in vergrössertem Massstab. 



   Der S-förmig profilierte und schraubenlinienförmig gewundene Kunststoffstreifen, aus welchem das Rohr hergestellt ist, ist mit 1 bezeichnet. An seinem nach innen liegenden   S-Bogenteil J ? ist eine über   den nachfolgenden S-Bogenteil   'hinübergreifende   Zunge 3 angespritzt. An den nach aussen liegenden SBogenteil 4 ist eine über den vorhergehenden   S-Bogenteil 4'hinübergreifende   Zunge 5 angespritzt. Hiebei entstehen je zwei Kammern, von welchen die Kammer 6 nach aussen hin und die Kammer 7 zum Rohrinnern hin öffnet. Die weitere Abdichtung wird durch das Anliegen der Zunge 5 am äusseren S-Bogenteil erreicht. 



   PATENTANSPRÜCHE : 
1. Biegsames Rohr aus einem schraubenlinienförmig gewundenen Kunststoffprofil mit S-förmigem Querschnitt, dadurch gekennzeichnet, dass an dem die Innenwand des Rohres bildenden Teil des Profiles   (1)   eine zungenartig ausgebildete, dem Verlauf der inneren Rohrwand folgende Verlängerung   (3)   vorgesehen ist.

   In Figs. 1 and 2 of the drawing, an embodiment of the subject invention is shown.



  1 shows the pipe, partially in section, and FIG. 2 shows a partial longitudinal section of the pipe on an enlarged scale.



   The S-shaped profiled and helically wound plastic strip from which the pipe is made is denoted by 1. On its inwardly lying S-bow part J? a tongue 3 extending over the following S-bend part is injection-molded. A tongue 5 extending over the preceding S-arch part 4 ′ is injection molded onto the outwardly located S-arch part 4. This creates two chambers each, of which chamber 6 opens to the outside and chamber 7 opens to the inside of the pipe. Further sealing is achieved by the tongue 5 resting against the outer S-bend part.



   PATENT CLAIMS:
1. Flexible tube made of a helically wound plastic profile with an S-shaped cross section, characterized in that a tongue-like extension (3) following the course of the inner tube wall is provided on the part of the profile (1) forming the inner wall of the tube.
