The present invention provides a faucet coupling structure capable of enabling a user to complete the faucet installation by simply inserting the faucet instead of rotating to tighten the faucet, and enabling the user to separate the faucet by holding and rotating the faucet by hand. The user can conveniently install the faucet while adjusting the angular orientation of the faucet to a desired angle. The user can install the faucet by holding and inserting the faucet by hand, and can also separate the faucet by holding and rotating the faucet by hand. As a result, the user can install and separate the faucet without using a tool.

A structure for coupling a faucet or a similar device includes: a faucet with a connecting pipe portion extending there-from; a connecting body with an annular coupling portion formed at one end and connected to a liquid supply source to discharge liquid through the faucet; a fastening nut screw-coupled to the annular coupling portion; a pressing ring coupled to the connecting pipe portion; and a grab ring configured to grab an outer circumference of the connecting pipe portion to have the connecting pipe portion not to be detached from the coupling portion. The fastening nut can be detached from the coupling portion by rotating the faucet and the connecting pipe portion with the engaging configurations of the pressing ring and the fastening nut in engaged position, and an angular position of the faucet can be adjusted to a preferred position in assembly by rotating the faucet and with the engaging configurations of the pressing ring and the fastening nut in disengaged position.

Disclosed herein is a fluid connection port for forming a working fluid connection between a deformable, flexible tube and a fluid handling device, the fluid connection port comprising a bore extending from an exterior surface of the fluid handling device to an internal fluid handling feature, the bore comprising a narrow diameter bore section adjacent the exterior surface of the fluid handling device, a larger diameter bore section adjacent the internal fluid handling feature, and a shoulder separating the narrow diameter bore section and the larger diameter bore section, wherein the diameter of the bore at the narrow diameter bore section is less than the outside diameter of the deformable, flexible tube.

A ferrule for a conduit fitting includes an interior wall extending along a central axis through the ferrule between first and second end portions of the ferrule, so that the ferrule can be installed over a conduit end. The first end portion of the ferrule includes an axially outer first end driven surface disposed at a first angle between 70° and 90° with respect to the central axis, and an axially inner first end camming surface disposed at a second angle between 0° and 40° with respect to the central axis. The second end portion of the ferrule includes an axially outer second end driven surface disposed at a third angle substantially equal to the first angle, and an axially inner second end camming surface disposed at a fourth angle substantially equal to the second angle.
