Embodiment Construction

[0026] The device selected as an example for fastening the hose is designed as a block-shaped hose clamp 1 consisting of two identically designed hose clamp halves 2 composed of.

[0027] In this exemplary embodiment, the hose clip half 2 is made of polypropylene (PP) and has a substantially square base body into which a semi-cylindrical shape is centrally formed in transverse direction. The void 21. In the inner side 22 of the clip half 2 , which is delimited by the recess 21 , two radially encircling grooves 23 with an arcuate cross section are formed spaced apart from one another. The transition between the groove 23 and the inner side 22 is of rounded design, so that a smooth surface without edges is formed. The corresponding transition of the inner side 22 formed by the recess 21 with respect to the end face 24 of the hose clip half 2 is likewise rounded and in particular edgeless.

[0028] Two bore holes 25 are bored into the hose clip half 2 on opposite sides of the ...

Abstract

The invention relates to a device for fastening hoses. The device comprises two fastening parts which can be connected to one another and which, in the assembled state, form a passage having an elliptical, in particular circular cross-section, wherein at least one radially encircling groove (23, 43) having an in particular edge-free cross-section is arranged in the inner lateral surface (22, 42) of the passage (11).

Description

technical field [0001] The invention relates to a device for fastening a hose according to the preamble of claim 1 . Background technique [0002] So-called clips are used for fastening pipes or hoses, which regularly include a clip body made of thermoplastic or elastomeric plastic or also of metal. The clip body is often formed here by two fastening parts which can be connected to one another, which in the assembled state form a channel for receiving a tube or a hose. Such clips are standardized in Germany according to DIN 3015:1999-01. For fixing the tubes, corrugated structures are used in particular. In this case, the inner surface of the channel is provided with radially surrounding ribs in order to increase the holding force. The received tube is held between the rib contact surfaces, thereby increasing the surface pressure. The tube is thus clamped in the clip. [0003] So-called H-profiles are used for fastening the hoses. In this case, the channel is formed as...
