- a wedge clamping ring 41 is provided with a conical inner surface 42.
- the wedge clamping ring 41 is adjusted according to the embodiment shown by means of clamping screws 43 which are arranged in threaded bores of an end bead 44 of the sleeve portion 11 and extend through this, against the cone-shaped projection 40 of the support ring 18.
- clamping screws 43 which are arranged in threaded bores of an end bead 44 of the sleeve portion 11 and extend through this, against the cone-shaped projection 40 of the support ring 18.
- FIG. 2 also shows that to minimize the dimensions of the housing 5 or the connecting sleeve 4, while ensuring the absorption of a high pull-out force, it is advantageously possible to provide at least one bridging element 45 spanning the wall cut-out 13 in the axial direction Sleeve section 11, on both sides of the wall cutout 14 releasably attached, eg is screwed.
- the front side of the beading 44 projecting through at least one, engaging in a threaded bore of the sleeve portion 11 screw the wall cutout 13 may be provided as a tie rod transverse.
- the pipe connection according to the invention can advantageously be used to connect pipes which are not directly part of fitting housings.
- Figures 4 and 5 largely correspond to Figures 1 and 3, wherein like reference numerals designate like parts.
- the connection sleeve 4 is seated on a connecting pipe 46. Otherwise, the description of FIGS. 1 to 3 applies to FIGS. 4 and 5.
- FIG. 6 The sectional view of FIG. 6 largely corresponds to that of FIG. 5, wherein it is shown how the sealing ring 34 can be connected via a connecting strip 58 with the retaining ring 18 and / or the upstream spacer 47.
- the spacer 47 serves to prevent the retainer ring 18 from being pushed toward the left edge of the inner groove when the wedge clamp is tightened to the left. If the spacer 47 is made of metal, the sealing ring 34 can be vulcanized with its existing rubber connecting strip 58 inside of the spacer 47. However, the connection strip 58 may also be connected to the retaining ring 18.
- Figures 7 and 8 show a further advantageous embodiment for the formation of an unfixed pipe connection, wherein here a retaining ring is disposed in an inner groove 12 of the connection sleeve and the retaining ring and the sealing ring are inserted through a slot-shaped wall cutout.
- Fig. 7 is an axial section through the pipe joint according to line VII.VII in Fig. 8 is shown.
- the pipe connection is made by a retaining ring, wherein an inserted into the inner groove 12 and plugged onto the insertion end 2 of the tube 3 clamping ring 48 is provided.
- Fig. 8 shows the advantageous embodiment of the inner groove 12 which is open by the fact that the wall cutout 13 is provided, through the pipe connecting elements, namely here the clamping ring 48, can be inserted before the insertion of the tube 3 is inserted.
- the wall cutout 13 extends over a cross-sectional sector whose internal angle is smaller than 180 °.
- the inner groove 12 leads in the closed area over a circular arc angle which is greater than 180 °.
- a tangential flattening 59 of the groove bottom of the inner groove 12 is provided.
- a slight Veren ⁇ tion of the wall cutout 13 may be provided, however, since the pipe connection elements to be inserted, as here, the clamping ring 48 is radially slotted and therefore is variable in its diameter.
- the clamping ring 48 has on its surface facing the tube peripheral surface on an annular groove 50 which has a flat rising wedge edge 51 and a steeply sloping stop edge 52. In this annular groove 50, a wedge ring 53 is inserted. The wedge ring 53 is radially slotted, as shown in Fig. 8, and therefore can change its radius.
- the clamping device 49 provided for the clamping ring 48 comprises a clamping tire 55 which is wrapped around the clamping ring and which has a tensioned screw connection 56.
