Description

One click fitting for connecting hose}

In general, fittings are fluids connected by connecting hoses. The types of fittings can be divided into fittings for communicating liquids (oil and water) and fittings for communicating gases (air and gas).

 Fittings applied to the double liquid can be divided into fittings made of plastic embedded in domestic water treatment devices, such as water purifiers, ionizers, water softeners, and fittings using urethane-based hoses used throughout industrial machines.

As one-touch fittings that are frequently used for liquids and gas bodies, FIGS. 1 and 2 are one-touch fittings (hereinafter, referred to in the related art).

 As shown, the prior art consists of a support (2) into which the hose (1) is inserted and a body (8) for fixing the support (2).

 The support 2 is composed of a plurality of holding front end engaging projections 3 which are elastically supported and provided at regular intervals when the hose 1 is inserted into a hole located at the center thereof.
