Abstract: Apparatus for joining an associated chain or leash and an associated generally horizontally cable which includes a pulley and a generally U-shaped frame having two leg shaped members extending in generally parallel spaced relationship with the free ends thereof being closely about the sides of the pulley. All of the other axial portions of the legs are spaced further apart than the free ends. An eye bolt has a generally circular head and a shaft which extends through the U-shaped frame. The shaft has a first spring seat fixed to the end of the shaft remote from the circular end. The shaft is disposed in generally parallel relationship to the first and second legs of the frame. A second spring seat is mounted on the surface of the U-shaped frame intermediate the first and second legs. A coil shaped compression spring extends intermediate the first and second spring seats and limits relative motion between the eye bolt and the frame.
