A corrugated protection pipe connector of a cable for an apartment house is provided to prevent a corrugated protection pipe from being separated by limiting rotations of two corrugated protection pipe connectors due to a rotation prevention tube. In a corrugated protection pipe connector of a cable for an apartment house, two corrugated protection pipes prevent water from penetrating into the inside by being sealed with a connection unit. The first corrugated protection pipe is fixedly inserted into a first corrugated protection pipe connector(20) by comprising the first corrugated protection connector(20), the second corrugated protection connector(40), an O-ring(50), a rotation prevention pipe(60), an external fixing pipe(70), and a putty. The second corrugated protection pipe is inserted into the second corrugated protection pipe connector(40). The rotation prevention pipe(60) is inserted not to rotate the first corrugated protection pipe connector(20) and the second corrugated protection pipe connector(40) with respect to each other. And, the external fixing pipe(70) seals between the first corrugated protection pipe connector(20) and the second corrugated protection pipe connector(40) by pressing the rotation prevention pipe(60) in a rear direction. |
