The in F i g. 3, the base body, which is represented by itself, is punched out between in the plane of the sheet metal piece 16 the clamping bracket 7 has the shape of a U-shaped remaining sheet metal tab 20.
In the tensioned position, the tensioning brackets 7 with angle bracket legs 9 grip hook-shaped from the hook-shaped angled ends 10 of the angled ends 10. In the case of the embodiment, bow leg 9 under the example of being rolled back in the shape of a channel, the base body of the clamping bow 7 is a flange edge 5 α of the container nozzle 5. Stamped sheet metal part bent into a U-shape. The bracket web 8 on the other side is the clamping screw 12 with which receives a clamping screw 12 in a pressure piece 15 connected with a collar passage 11 against the edge part 3 b of the threaded hole. flange 3 tightened. Here, the thrust piece engages the tensioning screw 12 has the embodiment 15 with its bends 18 and 19 via the wulsteinen hexagonal head 13 which additionally a b-like marginal portion 3 having the container flange 3, and screwdriver slot fourteenth leads to this. With the two sheet metal tabs 20

The free end of the clamping screw 12 has a pressure piece 15 that protrudes between the bracket legs 9

in Fig. 4, the pressure piece 15 shown for itself rotates into it and is thereby attached to the base body of the

movably riveted. This consists of the 20 clamping bracket guided secured against twisting.

Claims (3)

1 2 Embodiments are also known in which claims: the sealing edge part of the retaining flange between a flange of a container nozzle and a 1. Fastening device for clamped in liquid clamping ring, which is outside of the holding container from the outside to be inserted tubular heating flange 5 are penetrated by clamping screws. Even body with one of the heating tube ends through- in this' embodiment there are considerable set and with them firmly and tightly connected, radial dimensions, which often found disturbing z. B. welded or soldered retaining flange. '_, ·· ■■ the one object of the invention centering it in the installation opening is to provide a fastening to create a deep-drawn middle part and an outwardly io device of the type mentioned above, rolled back over a sealing ring, with simple manufacture and assembly, they do not have much impact fenden edge part has on the clamping means to space required in the radial direction. Pressing against the edge of the installation opening- This object is achieved according to the invention grip, characterized in that solves that the clamping means formed by clamping brackets the clamping means are formed by clamping brackets (7), the ends with hook-shaped angled ends are that with hook-shaped angled ends of two bracket web starting from a bracket web (10) two of a bracket web (8) outgoing legs under one rolled back to the outside Bracket legs (9) under an outwardly back flange edge of one that surrounds the installation opening rolled flange edge (5 a) grab the built-in container nozzle and in the bracket web a the opening surrounding the container nozzle (5) take up 20 clamping screws, which are and in the bracket web (8) a clamping screw (12) see the bracket legs and on the edge part of the record, which is rotatable with a pressure piece leading between the retaining flange Bracket legs (9) and on the edge part (3 b) of the is connected. Retaining flange (3) leading pressure piece (15) This means that the radial dimensions of the loading is rotatably connected. 25 fastening device practically down to the 2. Fastening device according to claim 1, reduced knife of the retaining flange. The clamps characterized in that the base body can be placed at any point on the circumference of the clamping bracket (7) a U-shaped bent and therefore set so that it is a tight ge-stamped sheet metal part (8, 9) is. group arrangement of radiators did not crowd 3. Fastening device according to claim 1 30 are a hindrance. In addition, compared to FIGS. 2 and 2, characterized in that the previously mentioned known embodiments provide a fitting (15) of the clamping bracket from a clamping screw (12) rotatably riveted with the eighth structural simplification and reduction in price and simplify handling.
Sheet metal piece (16) is made, which on each other against- The base body of the clamping bracket can be produced cheaply as overlapping ends for guiding on the edge- 35 U-shaped bent sheet metal stamping part. The part of the retaining flange is approximately at right angles from the pressure piece of the clamping bracket is preferably bent (bends 18, 19), namely at one end that is rotatably united with the clamping screw between two the guide on the riveted sheet metal piece that is on opposite bracket legs (9 ) accepting sheet metal tabs the ends for guiding on the edge part of the holding (20). 40 flange is bent approximately at right angles, namely at one end between two the guide to the - ^: Sheet metal tabs taking over the hanger legs. The invention is described below with reference to an embodiment shown in the drawing The invention relates to a fastening 45 example explained. It shows device for in liquid container from the outside F i g. 1 a fastening device according to the invention to be used tubular heating element with one of the devices in side view and partially in section,
The ends of the heating pipe are penetrated and fixed with them and F i g. 2 an end view, closely connected, e.g. B. welded or connected. 3 the main body of the clamping bracket, schaulöteten Retaining flange, the one him in the installation 50 figuratively, opening centering deep-drawn middle part and F i g. 4 the pressure piece of the clamping bracket, look rolled back outwards, over a you-figuratively. processing ring gripping edge part has on the clamping In the embodiment, the radiator means for pressing against the edge of the built-in six heating pipe ends 1, which engage a retaining flange 3 opening. ■. »:; ... ₅₅ enforce your jacket pipes behind the It is known seals the sealing edge portion of the holding pins 2 or brazed, the flange to the edge of the installation opening by means of the traversed by the Heizrohrenden central part 3 a of a clamping ring or some clamps presence of the retaining flange 3 is deep-drawn cup-shaped. The press closed, which are penetrated by the fixed outer edge part of the retaining flange 3 on the container wall for the on-screw bolts. These exceptions of a sealing guide form consisting of round material have the disadvantage that the press ring 4 rolled back a lot of space in an approximately semicircular outward fastening device in the radial direction. With the cylindrical outer surface of the claimed ^ what in a group arrangement of several deep-drawn middle part 3 α is centered the holding radiator can be a hindrance. In addition, flange 3 must be in the installation opening, which is often thickly framed by a container socket 5, for fastening the screw bolts. The flange plates walled with the container wall 6 are provided because it has welded or soldered container stubs 5 is not possible to weld the screw bolts directly to an outwardly rolled back flange 5 a on the sheet metal of the container wall. against which the retaining flange 3 with its sealing edge
