Claims (5)

1. Ausdehnbares Rohr mit einem Endverriegelungssystem für Boiler und dergleichen, das aus mindestens zwei Teilen (1, 2) besteht, von denen eines im Innern des anderen axial gleitet, dadurch gekennzeichnet, dass: nur der äußere Teil des Rohres (2) eine ringförmige Vertie­ fung (7) nahe an einem Ende aufweist, die den Rohrdurchmes­ ser verengt, der Außendurchmesser des inneren Teils des Rohres (1) gleich dem Innendurchmesser der Vertiefung (7) ist und der Endabschnitt (8) des einen Endes des Rohres derart aufgeweitet ist, dass sein Außendurchmesser größer als der Innendurchmesser der Vertiefung (7) ist, woraus sich ergibt, dass, wenn das ausdehnbare Rohr in der Stel­ lung maximaler Ausdehnung ist, der aufgeweitete Endab­ schnitt (8) des inneren Rohres (1) auf die Vertiefung (7) des äußeren Rohrs (2) trifft, wodurch verhindert wird, dass die beiden Rohre in zwei Teile auseinandergezogen werden.1. Expandable tube with an end locking system for boilers and the like, which consists of at least two parts ( 1 , 2 ), one of which slides axially inside the other, characterized in that: only the outer part of the tube ( 2 ) has an annular shape Vertie fung ( 7 ) close to one end, which constricts the Rohrmessmes ser, the outer diameter of the inner part of the tube ( 1 ) is equal to the inner diameter of the recess ( 7 ) and the end portion ( 8 ) of one end of the tube is expanded that its outer diameter is larger than the inner diameter of the recess ( 7 ), from which it follows that if the expandable tube is in the position of maximum expansion, the widened end section ( 8 ) of the inner tube ( 1 ) onto the recess ( 7 ) of the outer tube ( 2 ), thereby preventing the two tubes from being pulled apart in two parts. 2. Ausdehnbares Rohr mit einem Endverriegelungssystem nach Anspruch 1, dadurch gekennzeichnet, dass zusätzlich zu der Vertiefung (7) an einem Ende des äußeren Rohrs (2) ein ringförmiger Sitz (10) für eine Dichtung (9) vorgesehen ist, welche die Dichtheit der äußeren Oberfläche des inne­ ren Rohres (1) gewährleistet. 2. Expandable tube with an end locking system according to claim 1, characterized in that in addition to the recess ( 7 ) at one end of the outer tube ( 2 ) an annular seat ( 10 ) for a seal ( 9 ) is provided, which the tightness of the outer surface of the inner tube ( 1 ) guaranteed. 3. Ausdehnbares Rohr mit einem Endverriegelungssystem nach Anspruch 2, dadurch gekennzeichnet, dass die ringförmige Dichtung (9) aus einem O-Ring besteht, der in einen ring­ förmigen Sitz (10) eingefügt ist, der durch Verformung der Wand des äußeren Rohres (2) nahe an dem Ende erhalten wird.3. Expandable tube with an end locking system according to claim 2, characterized in that the annular seal ( 9 ) consists of an O-ring which is inserted into an annular seat ( 10 ), which is deformed by deformation of the wall of the outer tube ( 2nd ) is obtained close to the end. 4. Ausdehnbares Rohr mit einem Endverriegelungssystem nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass es einen Abstandshalter (4) enthält, der als Auflage dient und es gestattet, dass das Rohr im Innern eines äuße­ ren Rohres größeren Durchmessers eingepasst wird, um eine koaxiale Rauchgasleitung bzw. ein koaxiales Ofenrohr (5) zu bilden.4. Expandable tube with an end locking system according to one of the preceding claims, characterized in that it contains a spacer ( 4 ) which serves as a support and allows the tube to be fitted inside a larger diameter outer tube to a coaxial To form a flue gas pipe or a coaxial stovepipe ( 5 ). 5. Ausdehnbares Rohr mit einem Endverriegelungssystem für Boiler und dergleichen, wie oben beschrieben und darge­ stellt.5. Expandable tube with an end locking system for Boiler and the like, as described above and Darge poses.
