Abstract: A tether assembly for tethering an object, which tether assembly includes a cable having opposite ends and a connector attached to one of the opposite ends, and a retaining block for securing the cable to a support. The retaining block includes two parallel through-bores which extend through the retaining block and are provided for receiving the cable. The retaining block also includes a stepped bore which has a threaded portion and a non-threaded terminal portion. The non-threaded terminal portion of the stepped bore has a cylindrical portion which terminates at a common intersection with each of the two parallel through-bores, and a tapered end. A spherical element is positionable in the non-threaded portion of the stepped bore. In use, the retaining block is secured to a support structure and the connector is connected to an object to be tethered.
