Abstract: A fastener device for connecting a grid-like fence panel to a fence post comprises a helical rod presenting a plurality of ring elements therein. In the preferred embodiment, a vertical wire strand in the fence panel is placed adjacent the fence post with the helical rod being positioned so that the fence post protrudes through the lowest ring. Upon rotation of the rod, via a handle at the upper end thereof, the spiral rod winds itself about the fence post and wire elements adjacent thereto so as to join the fence to the post. A locking seat in the handle engages the top horizontal wire of the fence panel to hold the fastener device in place and preclude undesirable movement of the same away from its functional position. The fastener may be used to join a fence post to one or more wire panels and to join first and second wire panels to each other without the use of a fence post therewith.
