The utility model discloses a protecting connector for an oil-pipe transmission compound perforator. The protecting connector comprises a gun head, a middle connector and a gun tail, wherein the gun head is connected with one end of a perforating gun tube; the gun tail is connected with the other end of the perforating gun tube; the middle connector and the gun head are connected, so that two adjacent sections of perforating gun single tubes are connected into a whole; longitudinal overflow slots are formed in the protecting connector; and the longitudinal overflow slots are annularly distributed in an array form along the axis of the protecting connector. The protecting connector provided by the utility model can effectively prevent an external crushing cylinder and a well wall from being impacted and damaged and ensure that a perforating gun tube pillar is free from eccentricity during operation.
