A harness clamp to hold, position and mount multiple thermocouple wire sensors in a continuous casting mold tube. The anti-counterfeiting film comprises a directional retroreflective layer, an optical-angle-based color-changing information layer, a reflective layer and a support layer which are combined in this turn. The inner and outer sleeves include corresponding slots configured to align in response to relative movement of the inner and outer sleeves, and when aligned the slots of the inner and outer sleeves allow evacuation of fluid from the core catching tube as each of the plurality of formation cores is inserted into the core catching tube. The patterned layer has a plastic film and a pattern printed in a bottom surface of the plastic film. The plate has a pocket forming an axial-facing first abutment engaging the retaining clip and a radial-facing second abutment located outward of the retaining clip to prevent release of the retaining clip from the groove.
