PURPOSE: A connection unit for connection and prevention of separation of corrugated pipes is provided to connect the corrugated pipes easily and simply, to prevent connected parts from being easily deformed or deteriorated or connection from being released and separated by improving the uniting force of the connected parts, and to perfectly prevent invasion of moisture from the outside. CONSTITUTION: A connection unit for connection and prevention of separation of corrugated pipes comprises a connecting body(10), a screw shaft(20), a separation-preventing body(30), a cover(40), and a sealing member(50). The connection body comprises first and second body parts(10a,10b). Fixing pieces(11a,11b) in which plural combining holes(11') are pierced are projected to the upper ends of the first and second body parts. A hinge part(12) is formed to the lower end of the connection body. Fixing protrusions(13) are formed to the outer peripheral surface of one-ends of the first and second body parts and fitting protrusions(14) of a spiral shape are formed to the inner peripheral surface of the other side. The screw shaft is fitted into the combining holes and the screw shaft has a fastening nut(16). The separation-preventing body comprises third and fourth body parts(30a,30b). Fixing pieces(31a.31b) are projected to the upper ends of the third and fourth body parts. A hinge part(32) is formed to the lower end of the separation-preventing body. Fixing grooves(33) are formed to the front end parts of the inner peripheral surface of the third and fourth body parts. The cover of a rubber material is formed in a cylindrical shape and a part of the cover is incised. A spiral protrusion(41) is projected to the inner center of the sealing member. Inner and outer pieces(42,43) are formed to the sides of the sealing member.
