ABSTRACT:
First and second components can be releasably coupled together with a locking pin having a sacrificial o-ring. The first and second components have respective first and second openings that are aligned with each other and receive the locking pin. The second opening has a square edge located adjacent to a recess in the first opening. The o-ring has an outside diameter greater than the diameter of the square edge and an inside diameter less than the diameter of the square edge when assembled. The locking pin is inside of the first and second openings, with the o-ring inside of the recess. To release the components, the locking pin is moved out of the first opening to shear the o-ring against the square edge.
