A tube connection assembly comprises a male member, a female member and a mating member. The male member is provided with a retaining part that is formed with a non-circular cross-section on the outer peripheral part of a male body. The mating member is held by the retaining part, is formed from an elastic material having a C-shape, and has, on a portion thereof, mating parts. The female member is provided with a receiving part in which the male member is inserted, and mating holes and formed through the receiving part. The mating member is held, so as to prevent rotation, by a base part of a retaining part that has a non-circular cross-section as a part of the outer peripheral part of the male body, and decreases or increases in diameter in the radial direction to mate with the female member through insertion into the mating holes.

A hose clip for clamping a hose includes a clamping ring formed by annularly bending a strip of spring plate and deformed between a reduced-diameter state and a spread-diameter state. An arcuate portion is formed in either one of the ends of the clamping ring. A first knob is formed by bending the arcuate portion radially outward with respect to the clamping ring. A second knob is formed by bending the other free end of the clamping ring radially outward with respect to the clamping ring as so to pass through the arcuate portion. An engaged piece is formed on the one end of the clamping ring so as to project axially with respect to the clamping ring within a width of the spring plate. An engaging edge is formed on the other end of the clamping ring so as to move over the engaged piece and engage it when the first and second knobs are slid to come close to each other, thereby holding the clamping ring in the spread-diameter state with the knobs being substantially superposed. Also, a guide face is formed on a portion of the engaged piece with which the engaging edge engages. The guide face axially displaces the engaged piece and the engaging edge when the knobs come close to each other so that the engaged piece abuts the engaging edge.
