A device for connecting rods of a spine fixing system is provided to firmly support both rods while avoiding spinous processes during a surgical operation for spine, thereby realizing an easy assembling process by using collet members and nut members. The first and second collet members(110,120) are combined to surround external sides of both rods, and are capable of being elastically transformed. The first and second connection plates(210,220) comprise coupling holes(212,222) such that sections of the first and second collet members(110,120) can pierce through in both sections, while other sections thereof slide by a sliding unit, and are vertically combined together to be axially rotated. The first and second nut members(410,320) are coupled with the sections of the first and second collet members(110,120) piercing through toward top sides of the first and second connection plates(210,220), and pressurize external sides of the first and second collet members(110,120) with coupling forces.
