Abstract: The present invention relates to a connection coupling for fixing thin-walled hoses on a hose nipple. In the outer circumference of the hose nipple is formed an annular groove into which is pressed the hose pushed onto the hose nipple by means of a collar compressed by the coupling bolt lever lock, said bolt lever lock being fixed rotatably around an axis at said collar, said collar comprising a portion formed of a helical spring. The invention is characterized in that(a) a portion of said collar is formed of a half shell (4) comprising a central internal squeezed circumferential bead,(b) bolt lever lock (5) is articulated at one hand to half shell (4) and on the other hand to helical spring (6),(c) the length of helical spring (6) and the location of its fixing points (11, 13) at half shell (4) and at bolt lever lock (5) is adapted to an uninterrupted compression in closed condition also in the range of bolt lever lock (5).

Abstract: The invention relates to a coupling for pipes, tubes or hoses comprising shell portions connected by means of joint bolts and also comprising a bolt lever locking mechanism. Substantial improvement is obtained by the fact that the concerned web portion is part of an outer guide flange extending in a circumferential direction which engages the annular groove at a distance of at least 90.degree. before reaching the closing position. Integration of both web portions into a closed ring on the connecting flange represents a further advantage.

Abstract: The invention relates to a device for connecting two pipe ends, having a socket, a spigot and an annular seal therebetween. These parts are clamped together by flanges of a clamp in order to close the device. While prior art sockets and spigots have been made of massive material and shaped by expensive machining processes, the invention provides the spigot which is formed as a generally U-shaped profiled ring having a front and a rear annular flange and holding the sealing element between the flanges. The outside diameter of the front flange is smaller than that of the rear flange. The socket may also be a profiled ring in order to further reduce the manufacturing costs.

Abstract: The invention relates to a device to connect hose or pipe ends. Until now such a device comprised at least two non-deformable clamp parts with flanges extending inwards which serve to press a hose end onto a nozzle or which engage behind annular collars provided at the ends of the pipes. At the ends facing one another the clamp parts are provided with a mounting arrangement for a hinge-pin which connects these parts. To avoid the work entailed by providing such a mounting arrangement and by the assembling of a number of clamp parts, it is proposed according to the invention that the clamp-type ring is made as one piece and is produced of a material which can be deformed by hand and that the flanges are formed by a permanent shaping of the ring. In this way a far more inexpensive construction is obtained, which also has the advantage of a lower mass and requires less space.

Abstract: A coupling for connecting hose or pipe ends has a sleeve portion and a cylindric insert portion, each to be secured to one of the ends to be connected. The insert portion, when "plugged" in the sleeve portion, sealingly engages same to provide the coupling. The invention couples the two parts to prevent axial displacement of same. It utilizes a locking lever pivotable about a transverse axis and having a locking bolt at a location between the pivot and the free end of the lever. The pivot of the lever is mounted on a transverse cross-piece extending between free ends of the arms of a U-shaped frame surrounding the coupling. The base of the "U" has an upwardly protruding second bolt.

Abstract: The invention relates to a device for connecting flanged pipes. For this purpose, a multiple-section clamp is mainly used which includes inwardly protruding flanges engaging beyond the collars of the pipe ends. An annular profiled seal forms an approximately U-shaped hollow profile with the shanks which are formed as sealing lips and which abut against the peripheral surfaces of the collars. The assembly of the profiled seal is difficult. The sealing effect is often impaired by the peripheral surfaces of the collars being no longer sufficiently even and smooth. These drawbacks are removed by the invention such that the profiled seal has an inner profiled section extending between the faces of the collars and that the outer surfaces of the outer profiled section surrounding the peripheral surfaces of the collars are reinforced at a guide ring. Thus, the particular sealing region is disposed between the faces of the collars.

Abstract: A pipe coupling for coupling pipe ends to each other, one pipe end having at its end an annular shoulder limiting the sliding of a first sleeve member over the pipe end. The second sleeve member is so dimensioned that it fits over a piping end and is welded to same. The two sleeve members are insertable into each other such that a clamping shell comprised of two half-shells hinged to each other engages exterior shoulders of the sleeve members at a location wherein the two sleeve members are overlapped one by the other. Preferably, the second sleeve member is integral with a flange for connecting the member to an existing sleeve on the respective piping end. The invention results in a short overall structure facilitating the use of the coupling with flanged pipe connections of a piping system.
