Abstract
A fence formed of hollow fiberglass posts and rails. The posts have apertures formed therethrough transverse to their lengths for receiving the rails. Two hollow rails extend into an aperture from opposite sides of a post with their ends located in the aperture. A hollow connecting member is located within the two hollow rails for connecting together the ends of the two hollow rails. The hollow connecting member has a slit formed through its wall along its length and is compressed such that it may be located within the two hollow rails. The hollow connecting member when located within the two hollow rails expands outward against the walls of the two hollow rails.
