The traditional clamp type anchor must be improved when applied to CFRP (Carbon Fiber Reinforced Polymer/Plastics) prestressed tendons. The improved clamp type anchor consists of concave toothed curved clamps, anchor cups, plastic films, and thin-walled aluminum sleeves. In the design process of clip type anchors, the stress formula of the anchor cup is first derived through static analysis of the anchor. Then, the minimum thickness of the anchor cup is determined based on the Von Mises yield criterion, and the geometric size of the clip is obtained from the geometric relationship between the anchor cup and the clip. Experimental research shows that when the inclination angle of the anchor cup is 3 °, the pre tightening force of the clip is 100kN, the thickness of the aluminum sheet is 1mm, the spacing between the concave teeth is 12.85mm, and the depth of the concave teeth is 0.3mm, the clip type anchor shows good anchoring performance, with an ultimate load of 185kN and a corresponding anchoring efficiency coefficient of 96.4%. The experimental parameters such as anchor cup length, anchor cup inclination angle, pre tightening force of the clip, spacing between concave teeth, depth and width, and thickness of the aluminum sleeve all have a significant impact on the ultimate bearing capacity of the clip type anchor and the sliding amount between the CFRP reinforcement and the clip. The measured values of anchor cup stress are in good agreement with the theoretical values, verifying the reliability of anchor stress analysis. The calculation formula for ultimate load has good applicability
