Claim 4

A fence construction as claimed in claim 2, wherein each picket includes a first major pocket adjacent its first transverse link, the first major pocket being adapted to receive a first tongue, and a first minor pocket facing its respective first major pocket, with the transverse link extending between the minor and major pockets and being flush with a main part of the picket, the minor pocket being adapted to receive a free end of a respective tongue.

Claim 5

A fence construction as claimed in claim 3, wherein the transverse link of each picket is integral with a main portion of the picket.

Claim 6

A fence construction as claimed in claim 3, wherein each major pocket has a length greater than the length of the corresponding tongue.

Claim 7

A fence construction as claimed in claim 3, 4 or 5, wherein the first transverse rail is so dimensioned that, when the pickets are hung from the first transverse rail, the major pockets of the pickets are covered by the first transverse rail.

Claim 8

A fence construction as claimed in claim 1, which includes a second transverse rail, and wherein each picket includes one of a second tongue and a second mounting location which comprises a second, supporting part and a second transverse link of engaging a second tongue and having a width less than the height of the second tongue, and the second transverse rail is provided with one of a respective second mounting location and second tongue for each picket to enable each picket to be mounted to the first and second transverse rails.

Claim 9

A fence construction as claimed in claim 2, which includes a second transverse rail which is provided with second tongues, and wherein each picket includes a respective second tongues, and wherein each picket includes a respective second supporting part and a second transverse link for engaging a second tongue with the second tongue having a height greater than the width of the second transverse link, to enable each picket to be mounted on the first and second transverse rails.

Claim 10

A fence construction as claimed in claim 8, wherein each picket includes a major pocket adjacent its respective transverse link, the second major pocket being adapted to receive a second tongue.

Claim 11

A fence construction as claimed in claim 9, wherein the second transverse rail is so dimensioned that, when the pickets are mounted on the second transverse rail, the second major pockets are covered by the second transverse rail.

Claim 12

A fence construction as claimed in claim 9, wherein each second major pocket has a length greater than the length of a second major tongue.

Claim 13

A fence construction as claimed in claim 7, wherein the first tongues and first transverse links are so arranged as to prevent movement of the pickets in one vertical direction, and the second tongues and second transverse links are so arranged as to prevent movement of the pickets in the other vertical direction, thereby to form the retaining means for retaining the pickets in position.

Claim 14

A fence construction as claimed in claim 8, wherein the first transverse links and the first tongues are so arranged as to prevent movement of the pickets in one vertical direction, and the second tongues and second transverse links, are so arranged as to prevent movement of the pickets in the other vertical direction.

Claim 15

A fence construction as claimed in claim 13, wherein the first tongues are directed upwards, and prevent movement of the pickets downwards, and the second tongues are directed downwards, and prevent movement of the pickets upwards.

Claim 16

A fence construction as claimed in claim 2, 3 or 14, wherein each of the first transverse rail, the second transverse rail and the pickets is formed from sheet metal.

Claim 17

A fence construction as claimed in claim 1, 2 or 8, wherein the retaining means comprises a cover rail adapted to cover the first transverse rail and tops of the pickets, and the first tongues and first transverse straps are arranged to prevent downward movement of the pickets, whereby, with the pickets assembled on the first transverse rail and the cover rail in position, the cover rail prevents removal of the pickets.

Claim 18

A fence construction as claimed in claim 8, wherein the first and second tongues are directed upwards, to prevent downward movement of the pickets, and wherein the retaining means comprises a over rail adapted to cover the first transverse rail and tops of the pickets, so that with the pickets hung on the first transverse rail, the cover rail prevents removal of the pickets.

Claim 19

A fence as claimed in claim 1, wherein the first tongues have tapered sides, the sides being furthest apart at the base of each tongue.

Claim 20

A fence construction as claimed in claim 8, wherein each picket includes: a first major pocket adjacent its first transverse link, the first major pocket being adapted to receive a first tongue, and a first minor pocket facing its respective first major pocket, with the first transverse link extending between the first minor and major pockets and being flush with a main part of the picket, the first minor pocket being adapted to receive a free end of a respective first tongue; and a second major pocket adjacent its respective second transverse link, the second major pocket being adapted to receive a second tongue, and a second minor pocket facing its second major pocket, with the second transverse link extending between the second minor and major pockets and being flush with a main part of the picket, the second minor pocket being adapted to receive a free end of a respective second tongue.

Claim 21

A fence construction as claimed in claim 7 or 19, wherein the first tongues and first transverse links are arranged to restrain the pickets from movement downwards, and the second tongues and second transverse links are arranged to restrain the pickets from movement upwards thereby to form the retaining means for retaining the pickets in position.

Claim 22

A method of assembling a fence construction as claimed in claim 20, the method comprising the steps of: (a) after providing support ports, securing the first transverse rail to the support posts with the first tongues directed upwards; (b) hanging the pickets on the first transverse rail, with the first transverse links engaging the first tongues; (c) engaging the second tongues of the second transverse rail with the second transverse links; (d) securing the second transverse rail to the posts to retain the pickets in position.

Claim 23

A method of assembling a fence construction as claimed in claim 20, the method comprising the steps of: (a) after providing support posts, securing the first transverse rail to the support posts; (b) mounting the pickets on the first transverse rail, with the first transverse links engaging the first tongues; (c) mounting the cover rail on the first transverse rail and securing the cover rail in position, to retain the pickets.
