PURPOSE: A connection fitting for preventing the separation and fatigue failure of hoses is provided to prevent the bursting of the hoses caused by the fatigue failure or torn hoses when the separation pressure is applied to the hoses. CONSTITUTION: A connection fitting for preventing the separation and fatigue failure of hoses has an array structure in which first and second end protrusions and first and second end connection protrusions are alternated. The minimum distance (D1) between the first and second connection protrusions, the distance (D2) between the first end connection protrusion and a tube unit (16), the minimum distance (D3) between the second end protrusion and the second end connection protrusion, and the distance (D4) between the second end connection protrusion and the tube unit satisfy equation 1: D1<=D2, D4<=D3, D2<=D4. |
