Problems solved by technology

If a torque is applied to the hose guide and the connecting pipe is twisted relative to the hose guide, there is the danger that the at least one annular flange is buried in the inner circumference of the hose of the hose guide, which would interfere with the hose guide. The looseness or reduced resistance to breakage associated with

Embodiment Construction

[0035] exist Figures 1 to 5 A hose coupling 1 is shown in , which is used to connect a flexible hose 2 , for example, to a stop valve or to a sanitary outlet fitting or similar water consumption point. The sleeve-shaped hose coupling 1 has, on at least one coupling end, a connecting piece 3 which has a retaining profile on the outer circumference at least in the region of the socket part.

[0036] as in Figures 2 to 5 As can be seen in , the hose end 4 of the flexible hose 2 can be pushed onto the at least one formed coupling end. The retaining profile provided on the connecting pipe 3 of the hose coupling 1 is formed by at least one and preferably—as here—by a plurality of retaining grooves 5 arranged on the outer circumference of the connecting pipe 3 . Each of these retaining grooves 5 formed as recesses into the outer circumference of the socket has narrow groove sides 6 , 7 oriented in the longitudinal direction of the socket and long groove sides 8 , 9 oriented in t...

Abstract

The invention relates to a hose coupling (1) which is designed in the form of a sleeve and which has, on at least one coupling end, an outer circumferentially arranged Holding the profiled connecting tube (3), the hose end (4) of the flexible hose (2) can be pushed onto the at least one profiled coupling end. The hose coupling according to the invention is characterized in that the retaining profile is formed by at least one retaining groove (5) arranged on the outer circumference of the connecting pipe (3), said retaining groove having a The long sides (8, 9) of the slots and the narrow sides (6, 7) of the slots oriented longitudinally of the nozzle.

Description

technical field [0001] The invention relates to a hose coupling which is designed in the form of a sleeve and which has, on at least one coupling end, a retaining profile which is arranged on the outer circumference at least in the region of the connection part. The hose end of the flexible hose can be pushed onto the coupling end. Background technique [0002] Instead of thin copper pipes, flexible hose lines are gradually being used in the sanitary sector in order to supply water, for example, from angle valves to wash basins or similar water consumption points. A hose coupling of the type mentioned at the outset is required to connect a flexible hose to an angle valve or similar water supply line and / or water consumption point. [0003] Previously known hose couplings are usually designed in the form of a sleeve and have a connecting thread or union nut at one end, while a connecting tube is provided at the other coupling end. The connecting pipe has a retaining profile...
