Gemäß den Zeichnungen ist eine zylindrische Httlse 10 aus Kunststoff oder einem anderen elastischen Material vorgesehen, die an ihrem Außenumfang eine oder mehrere Umfangsrippen 11 hat, mittels derer sie in die Innenwand eines zylindrischen Stutzens eingreift, ausgebildet beispielsweise als der bei 12 in Fig. 2 geseigte Teil. In diesen Stutzen wird sie eingesetzt. Der Innenumfang der Hülse 10 hat in der Nähe ihres äußeren Endes eine Partie 13 ein konischer Form, die in Sichtung auf das äußere Ende des Stutzens zuläuft. Am inneren Ende der Hülse 10 ist eine zylindrische Muffe aus elastischem Kunststoff oder aus einem sonstigen Material vorgesehen, wobei der Außenunfang der Muffe 14 an dem äußeren Ende abgesetzt ist, um stramm in das innere Ende der Hülse 10 in überlappender Lage zu passen, wobei die größere Partie der Muffe I4 einen Durchmesser hat, der gleich dem der Hülse 10 ist, ebenso dem der Innenwandung des Stutzens, in den sie eingesetzt werden soll. Ferner ist an dem Innenumfang der Muffe an ihrem inneren Ende ein Hingflansch 15 vorgesehen, der ein Widerlager für ein eingesetztes Rohr bildet.According to the drawings, a cylindrical sleeve 10 is made of plastic or another elastic material is provided which has one or more circumferential ribs 11 on its outer circumference, by means of which it engages in the inner wall of a cylindrical connecting piece, designed for example as the part sloping at 12 in FIG. In this nozzle is used. The inner circumference of the sleeve 10 has near its outer end a portion 13 of a conical shape, which runs towards the outer end of the nozzle in sight. On the inside At the end of the sleeve 10, a cylindrical sleeve made of elastic plastic or some other material is provided, the outer periphery of the sleeve 14 being offset at the outer end to tightly fit in to fit the inner end of the sleeve 10 in an overlapping position with the larger portion of the sleeve I4 having a diameter which is equal that of the sleeve 10, as well as that of the inner wall of the connecting piece into which it is to be inserted. Furthermore, on the inner circumference of the Sleeve provided at its inner end, a hanging flange 15, which is a Forms abutment for an inserted pipe.

Innerhalb des äußeren Endes der Hülse sitzt eine Muffe bzw. ein Futter 16 aus Kunststoff oder einem anderen elastischen Material, bestehend aus zwei im wesentlichen halbxylindrisehen Teilen, die an ihren Außenflächen konische Partien haben, welche komplementär zu den konischen Partien 15 der Hülse 10 sind. Ferner ist am Innenumfang des Futters eine Umfangerippe 17 zum Angreifen an einem aufgenommenen Rohr Torgesehen. Zwischen dem inneren Ende des Futters 16 und der Muffe sitzt in der Hülse 10 ein elastischer Dichtring 18 mit einem Durchmesser zur Herstellung einer mediumdichten Verbindung um das eingesteckte Bohr, was noch xm beschreiben sein wird.Inside the outer end of the sleeve sits a sleeve or a lining 16 made of plastic or another elastic material, consisting of two essentially semi-cylindrical parts which have conical parts on their outer surfaces which are complementary to the conical Parts 15 of the sleeve 10 are. It is also on the inner circumference of the lining a peripheral rib 17 for engaging a received tube gate. Between the inner end of the chuck 16 and the sleeve sits in the sleeve 10 an elastic sealing ring 18 with a diameter for Creation of a medium-tight connection around the inserted drill hole, what else will be described xm.

In Fig. 2 ist der feil 12 als ein Kupplungsglied gezeigt, bestehend aus zwei koaxialen zylindrischen Stutzen, die durch einen Inesnflanseh 19 getrennt sind und die jeweils eine der in I1Ig. 1 gezeigten Einheiten enthalten. Die Xinheiten können jedoch auch in Stutzen eingesetzt werden, die in Kupplungen von Knie- T-Stücken oder dergleichen vorgesehen sind. Zweckmäßigerweise hat der Stutzen Innennuten in seiner Wandung zur Aufnahme der Bippen 11 dear Hülse, so daß dann, wenn die Ein-In Fig. 2, the feil 12 is shown as a coupling member, consisting of two coaxial cylindrical sockets, which are separated by an Inesnflanseh 19 and each one of the I 1 Ig. 1 included. The units can, however, also be used in nozzles which are provided in couplings of knee T-pieces or the like. Appropriately, the socket has internal grooves in its wall for receiving the ribs 11 dear sleeve, so that when the input

Wenn bei Gebrauch ein Rohr entsprechenden Durchmessers (d.h. mit einem Durchmesser, zum strammen Passen in die. Muffe I4) in die Kupplung geschoben worden ist, bis es sich gegen den Plansch 15 legt, stellen sich die Sippen 17 am Futter irgendeinem Zug auf das Rohr entgegen, der bestrebt ist, es herauszuziehen* dabei graben sich die Rippen in das Rohr als Folge der Wechselwirkung der komplementären konischen Flächen des Futters und der Hülse. unit is inserted into the socket "until the socket I4 rests against the flange 19, removal of the unit is not easily possible ) has been pushed into the coupling until it lies against the surface 15, the ribs 17 on the lining oppose any pull on the pipe that tries to pull it out * the ribs dig into the pipe as a result of the interaction of the complementary conical surfaces of the chuck and the sleeve.

Gegebenenfalls kann eine Schraubendruckfeder zwischen den Dichtring 18 und das Futter 16 gesetzt werden, um die komplementären konischen Partien der Hülse 10 und des Futters in Kontakt miteinander zu drücken.If necessary, a helical compression spring can be placed between the sealing ring 18 and setting the chuck 16 to force the complementary conical portions of the sleeve 10 and chuck into contact with one another.
