<p>PURPOSE: To tighten the insertion part in the tip of a tube surely, not relating to the thickness thereof by providing a sleeve shape tubular coupling installed on at least one part thereof. CONSTITUTION: On the outside of the tubular coupling 5 of a sleeve 2, a radially expanded wave shape 6, whose right side shape is a truncated cone, is provided. The inclination of the wave shape truncated cone is equal to that of four flexible prong shape coupling elements 7 and the sleeve 2 can be inserted easily into the tip of a hose 1, as the prong 7 has a wave shape 6 structure with the inclination. A clamping member 3 surrounds the tip of the hose 1 staying between the wave shape 6 and the tip of the sleeve 2 freely opened to the outside.</p> |
