Abstract
A chain master link has first and second link parts having outer ends centered on respective substantially parallel first and second axes and coupled-together inner ends. Each inner end is formed with at least one tooth extending transversely across a plane including the two axes and having an inner face turned toward the respective axis and forming with the plane an angle of at least 90° open away from the respective axis. The teeth are engaged together with the inner faces bearing on each other so that tension pulling the parts apart along the plane pulls the teeth into engagement with each other. Each part is formed with a pocket receiving the tooth of the other part and having an outer face forming with the plane an angle open away from the respective axis and greater than the respective inner-face angle. Thus the two parts can be fitted together simply by pivoting their inner ends toward each other about the respective outer-end axes.
