An electric fence insulator assembly configured for attaching to tree trunks, pipes, posts and t-posts of various size, shape and materials is disclosed. The electric fence insulator assembly comprises two panels disposed at an obtuse angle and connected by a connecting member containing a clamp. Attached to the rear of each panel is a cord gripping member. The electric fence insulator assembly is fitted between the two panels and an elasticized cord wraps around the tree trunk, pipe or post, then wedged into the first gripping member at one end and wedged into the second gripping member at its other end. This configuration minimizes the contact area of the electric fence insulator assembly with the tree trunk. The shape of the insulator is designed to maximize stability and provide a secure attachment to trees, pipes and posts. A stretchable cord allows for expansion and adjustability as the tree grows.
