This utility model relates to the field of power transmission equipment technology, specifically to a clamp device for spacers and a phase-to-phase spacer assembly. The device includes a clamp body and a pressure cap. One end of the clamp body is used to connect to the spacer; one end of the pressure cap is rotatably mounted on the clamp body, forming two clamping plates. A wire hole for holding the wire is provided between the pressure cap and the clamp body. A locking part is provided at the other end of the pressure cap. The clamp body has a sliding groove, within which a locking pin slides. When the locking pin slides to the end of the groove near the pressure cap, it abuts against the locking part when the pressure cap is closed, thus restricting the pressure cap from rotating open. When the locking pin slides to the other end of the groove, it disengages from the locking part. The clamp body has an elastic element, with its two ends abutting against the locking pin and the clamp body respectively. Applying external force to push the locking pin and compress the elastic element allows the pressure cap to be opened and the power transmission wire inserted. After closing the pressure cap, removing the external force pushes the elastic element to push the locking pin against the locking part, preventing the pressure cap from loosening. This design is convenient to use.
