Embodiment Construction

[0025] FIG. 1 shows a hose connection 1 , by means of which a hose 2 is connected to a line 3 . The hose 2 and the pipe 3 form a fluid conduit for a pressurized fluid, wherein the bursting pressure can for example exceed 100 bar (for example 140 bar). A hose connection part 4 integrally formed at the end of the pipe 3 belongs to the hose connection device 1 , as shown separately in FIG. 6 . As mentioned above, the hose connection part 4 can form the end of the pipe 3 or can be configured as a separate nipple, on the left side of which (refer to FIG. screw or other coupling mechanism.

[0026] The hose connection part 4 is tubular and has a hose receiving section 5 . The outer surface of the hose receiving section is provided with a profiling. Starting from a cylindrical basic shape, the end has a chamfer 6 in order to facilitate the insertion of the hose connection part 4 into the open hose end. Furthermore, one or more annular ribs 7 , 8 are provided on the outer surface ...

Abstract

The invention relates to a tube connection (1) which uses a retainer (17) for fastening a tube end to a tube connection element. The retainer (17) is anchored to a flange (14) of the tube connection element (14) and comprises two retaining limbs (18, 19) that are anchored on the outside of the tube (2) by means of tightening straps (34). The retaining limbs (18, 19) rest between the outside of the tube (2) and the tightening straps (34) and are clamped therein. The retaining limbs have recesses with the flanges or stepped edges of which they are positively supported on the tightening straps (34). The tightening straps (34) dig into the outside of the tube (2) and therefore also rest positively against the tube. The invention provides a reliable and inexpensive connection between the tube (2) and for example a conduit (3), which is easy to produce.

Description

technical field [0001] The invention relates to a connection device for connecting a hose to a nipple, a pipe end or the like. Background technique [0002] In many technical fields—for example, in hydraulic equipment, air conditioning equipment, heating and ventilation equipment, automotive technology, etc., it is necessary to establish a fluid-tight, durable and reliable connection between hoses and connected pipes or components or other structural units. connect. In this case, the reliability of the connection, the long-term tightness against the fluid flowing in the pipe or hose, the assembly reliability and the simplicity of establishing the connection are of great importance. [0003] From utility model document Nr. 7314756 it is known that a hose with an inner bellows is fastened by means of a crimp sleeve to a corresponding nipple which fits into the bellows. The crimp sleeve is pushed onto the portion of the bellows that does not have the outer hose jacket. [00...
