<p>The fluid line has conical portion (9) formed at one end and adjacent to undulated region (8), whose outer diameter increases in direction towards free end such that it is greater than shaft diameter of main portion (6). The wall of end portion of fluid line is stiffer than entire wall of main portion of fluid line. The fluid line has conical portion formed at one end and adjacent to undulated region, whose outer diameter increases in direction towards free end such that it is greater than shaft diameter of main portion. The fluid line has sealing ring receiving groove at its intermediate portion (10) and a holding rib for engaging locking projection of pipe-connection ring. The outer diameter of the intermediate portion decreases from maximum diameter of conical portion to the minimum diameter of locking-projection engagement groove. The wall of end portion of fluid line is stiffer than entire wall of main portion of fluid line. The wall thickness of end portion of fluid line is twice the wall thickness of main portion of fluid line. The end portion of fluid line comprises reinforcement materials such as glass fiber, mineral fiber, metal fiber and glass spheres. An independent claim is included for pipe/fluid-line connection arrangement.</p> |
