The design and construction of past piston pin assemblies includes a retaining device which adds stress concentration factors to the piston pin assembly, piston skirt or piston crown. The present invention provides a device for retaining the piston assembly to the connecting rod and retaining the two parts of the piston pin assembly together without adding a stress concentration factor. The device uses a retaining means which applies a compressive force along the entire piston pin to add rigidity to the piston pin assembly. This design additionally allows for a stronger piston assembly with greater pull apart resistance and/or a lighter total weight piston assembly.
