    undTrägerkörper-25-in   die Ausgangslage zurück. 



   Im Rahmen der Erfindung sind selbstverständlich verschiedene Abänderungen der vorbeschriebenen
Ausführungsbeispiele möglich. 



   So könnte z. B. wie in Fig. 3 angedeutet ist, der Arm --22-- des Kniehebels nach aussen durch den   Fortsatz --38-- verlängert   sein und die Kraft statt bei --34-- bei --39-- auf den Fortsatz --38-- auf- gebracht werden. Damit wäre einerseits durch den Hebel --38-- eine Übersetzung erreicht. anderseits könnte nach Erreichung der Strecklage des   Kniehebels --22, 23-- das Lagerstück --33-- bei   gestrecktem
Hebel nach unten bewegt und so ein Abrollen der   Stirnfläche-26-,   die grösser als gezeichnet ausge- bildet sein könnte, an der   Aussenhülse-28-- erzielt werden.   



   Wie aus den gezeichneten Ausführungsbeispielen ersichtlich, ist für die Erfindung die Kniehebel- wirkung und das anschliessende Abrollen wesentlich. Dadurch wird nämlich die zum Eindrücken erforder- liche Gesamtkraft aufgeteilt, weil der zum Festhalten erforderliche Eindruck nicht auf einmal herge- stellt wird. 



   PATENTANSPRÜCHE : 
1. Vorrichtung zum Verbinden von Hochdruckschläuchen mit Anschlussmuffen, die aus einer druck- festen Innen- und einer verformbaren Aussenhülse bestehen, zwischen welchen Hülsen das Schlauchende dichtend eingeklemmt wird, wobei die Vorrichtung mehrere, in einem Tragkörper radial zur Muffe be- wegbar gelagerte Druckkörper aufweist, die an die Aussenhülse der Muffe zu deren bleibender Verfor- mung angepresstwerden, dadurch gekennzeichnet, dass die Druckkörper (9, 22) in Radial- ebenen zur Muffe (6,28) schwenkbar und kniehebelartig an die Muffe anpressbar sind, wobei die Druck- körper als Kurvenscheiben (9) oder als der eine der beiden Arme eines Kniehebels (22, 23) ausgebildet sind.

    and support body-25-back to the starting position.



   Various modifications of those described above are of course within the scope of the invention
Embodiments possible.



   So could z. B. As indicated in Fig. 3, the arm --22-- of the toggle lever can be extended outward through the extension --38-- and the force is applied to the extension instead of --34-- at --39-- --38-- are applied. On the one hand, this would achieve a translation through the lever --38--. on the other hand, after reaching the extended position of the toggle lever --22, 23-- the bearing piece --33-- with the extended
The lever is moved downwards and so the end face -26-, which could be made larger than shown, can roll on the outer sleeve -28-.



   As can be seen from the illustrated embodiments, the toggle lever action and the subsequent rolling are essential for the invention. In this way, the total force required for pressing in is divided up, because the impression required for holding is not produced all at once.



   PATENT CLAIMS:
1. Device for connecting high-pressure hoses with connecting sleeves, which consist of a pressure-resistant inner sleeve and a deformable outer sleeve, between which sleeves the hose end is tightly clamped, the device having several pressure bodies mounted in a support body so that they can be moved radially to the sleeve , which are pressed against the outer sleeve of the socket for permanent deformation, characterized in that the pressure bodies (9, 22) can be pivoted in radial planes relative to the socket (6, 28) and can be pressed against the socket in the manner of a toggle, whereby the pressure body as cam disks (9) or as one of the two arms of a toggle lever (22, 23).

Claims

2. Apparatus according to claim 1, characterized in that the pressure body as Disc segments (9) are formed and the supporting body is a cylindrical sleeve (12) which can be displaced with respect to the stationary hose sleeve (2,6).

3. Apparatus according to claim 1 or 2, d ad urch gekennz eichn et that the support body is provided at one end with pressure rollers (15) on which a rotatable cam disc (17), helical surface or the like, which causes the axial movement, rests.

4. Device according to one of claims 1 to 3, characterized in that the cylindrical support body (12) is guided in an outer fixed, advantageously the displacement of the support body causing elements (cam 17) containing, expediently cylindrical bearing body (14) .

5. Device according to one of claims 1 to 4, characterized in that the support body (12) against the force of one or more springs (19) or the like, which cause a return to the starting position after the working stroke, is movable.

6. Device according to one of claims 1 to 5, characterized in that the support body (12) and bearing body (14) are divided along an axial plane through the sleeve axis (8) and can be opened around a common joint for introducing the sleeve into the working position.

7. Device according to claim 1, characterized in that the pressure bodies (22) form one arms of toggle lever pairs (22, 23), the common connecting joint (24) of which is mounted in a movable support body (25), with the pressure bodies forming the appropriate ones Arms are each slidably mounted in a pivotable guide piece (29), whereas the free end of the other articulated arm (23) is attached to a counterpart (33) which is fixed with respect to the support body (25).

8. Device according to one of claims 1 to 7, characterized in that the pressure surfaces (21, 26) of the pressure pieces (9, 22) are profiled corresponding to the radius of the lateral surface of the outer sleeve (6, 28).
