Abstract:
1. A pipe system comprising: a pipe fitting; a pipe receivable in the pipe fitting from a holding bore at an end of the pipe fitting; a C-clip received in a circumferential groove at an outside of a sidewall of the pipe, wherein the C-clip has an arc structure with two opposed finger ends separable from each other so as to be allowed for expansion and contraction, wherein the C-clip contacts an inner wall of a space in the pipe fitting, wherein the inner wall has a sloped surface and has a diameter greater than that of the holding bore, wherein multiple openings at a sidewall of the pipe fitting correspond in position to the C-clip such that the pipe is detachable from the pipe fitting by multiple projections passing through the openings and forcibly contracting the C-clip so as to reduce a diameter of the C-clip; and a sealing ring received in a groove at an inside of the sidewall of the pipe fitting, wherein the sealing ring is farther away from the holding bore than the C-clip.
