The application relates to a wire harness clamp and relates to the technical field of wiring devices, which comprises a wire restraint part and a fixing seat, the wire restraint part comprises a first wire harness part, a connecting part and a second wire harness part connected in sequence, the connecting part has flexible deformation bending, the first wire harness part is clamped with one end of the second wire harness part away from the connecting part, and a partition plate is arranged in the wire restraint part to separate the internal space. A physical isolation barrier is constructed in the wire restraint part through the partition plate, different groups of wires are placed in different partition channels, and the technical defects of cross winding of different path wires are eliminated in structure; meanwhile, the spatial arrangement of the wire harness is optimized, and a grouping identification basis is provided for subsequent maintenance.
