PROBLEM TO BE SOLVED: To provide a means for junction of two spaced elongated rods of a human spine implant having a simple structure and capable of being imbedded quickly. SOLUTION: The connecting means has a mouth-shaped portion and a hook 14 to hold the surrounding of the first rod, a bar 12, and a holding means connected to the second rod and mounted to the bar 12. The bar 12 and the hook 14 are interconnected through a joint 20. The joint has a joint portion that can rotate between releasing and fixing positions. To prevent the joint portion of the hook 14 from rotating to the releasing position, a fixing means 28 is provided. In the joint portion connected to the bar 12, the first rod is fixed in the mouth-shaped portion in the fixing position and a hook having the mouth- shaped portion is mounted freely on the first rod in the releasing position.
