Abstract
A fastening device for connecting a tension member to an object, whereby a force can be applied to the object in any direction within a hemisphere centered about the point of attachment to the surface of the object. The swivel shackle comprises a shoulder bolt which is adapted to be attached to the object and has a cylindrical portion of larger diameter than the base portion which is attached to the object, as by threads. A unitary load ring comprises a body portion having a circular bored opening adapted to rotate on the cylindrical portion on the bolt. The load ring has two oppositely directed shafts extending from the body portion. A Y-shaped pivot assembly is provided which has an opening in each of the arms of the Y, which are adapted to fit over and rotate about the shaft extension on the load ring. The leg of the Y has an opening, to which a shackle can be attached, by passing the pin of the shackle through the opening in the leg of the Y.
