Abstract
A connector for securing adjacent pile sections, or other pipe sections, to each other, including a box disposed over a pin, with the end of the box engaging a companion pin shoulder, the pin and box being rigidly secured together by a plurality of lock dogs forced radially within companion grooves in the pin, the dogs and grooves having coengaging cam surfaces exerting an axial thrust between the box end and pin shoulder upon inward movement of the dogs, to provide a large bearing area and preload between the pin and box under substantial compression to prevent separation between the pin and box due to rebound during the pile driving operation.
