Claim 14

A fence as claimed in claim 9 in which said reinforcing inserts are metal members selected from metal channels and tubes.

Claim 15

A fence as claimed in claims 8, 9 or 10 in which said extruded thermoplastic posts, rails and vertical members are extruded to provide a core containing reprocessed thermoplastic material and a protective co-extruded cap stock covering exposed exterior surfaces thereof.

Claim 16

Claim 17

Connector means for connecting a fence rail to a fence post comprising a hanger member having mounting means for attachment to the post, said mounting means supporting a planar tongue spaced away from said mounting means and having spaced groove engaging edges, and a plastic bracket member having a first end portion to fit over and conceal said hanger member and having spaced internal grooves to receive and interlock with said spaced tongue edges, and a second tubular end portion to receive the ends of a fence rail.

Claim 18

Connector means for connecting a fence rail to a fence post comprising a hanger member having mounting means for attachment to the post, said mounting means supporting a planar tongue spaced away from said mounting means and having spaced groove engaging edges, and a plastic bracket member having a first end portion to fit over and conceal said hanger member and having spaced internal grooves to receive and interlock with said spaced tongue edges, and a second tubular end portion to receive the ends of a fence rail.
