A lock pin mechanism for a negative "G" pilot's harness includes a contoured strap lug received within a metal keeper. A lock pin passes through the keeper and engages the lug. A bearing surface exists between the lug and the keeper so that high upward forces exerted on a negative "G" strap are transmitted to the strap lug but become shared between a lug-pin interface as well as a lug-keeper interface. Thus, binding frictional engagement between pin and lug is avoided so that safe and secure withdrawal of the pin is achieved when required.
