- the first and second elongate members 12 and 14 are linear and define axially extending grooves 20 to reduce the amount of material required to mould the first and second elongate members 12 and 14.
- the first and second elongate members 12 and 14 are made from an electrically non-conductive, polymeric material, preferably a glass fibre reinforced nylon.
- electrically non-conductive is intended to mean a material with conductivity lower than 0.001 Siemens per meter, in the preferred embodiment, the actual conductivity of the material is lower than 0,0001 Siemens per meter, even as low as 10E-13 Siemens per meter.
- first and second elongate members 12 and 14 have been shown as being generally square in axial cross-section, it will be appreciated that the fsrst and second elongate members 12 and 14 could be of any other cross-sectional shape, e.g. rectangular, polygonal or circular.

- a female connecting formation 24 is integrally formed at a first axial end of each of the first and second elongate members 12 and 14.
- the female connecting formation 24 comprises an axially extending cavity, and a pair of bores 26 defined by its radial wall.
- a male connecting formation 28 is integrally formed at a second axial end of each of the first and second elongate members 12 and 14.
- the male connecting formation 28 comprises a spigof that is sized and shaped to be received within the cavity defined by the Female connecting formation 24, and a pair of nippies 30 fhat protrude radially from the spigot.
- the nippies 30 are sized and shaped to be received within the bores 28 defined by the radial wail of the female connecting formation 24 when the male connecting formation 28 is received within the female connecting formation 24.
- the nippies 3Q and boras 28 comprise locking means for locking the male connecting formation 28 to the female connecting formation 24 when the male connecting formation 28 is received within the female connecting formation 24. Mote specifically, when the nipples 30 are receives within the bores 28, capture of the nipples 30 within the bores 28 locks the male connecting formation 28 to the female connecting formation 30.
- each nipple 30 (proximal the free end of the spigot) is chamfered to facilitate resilient deformation of the male connecting formation 28 during reception of the male connecting formation 28 within the female connecting formation 24,
- Both the first and second elongate members 12 and 14 include wire connecting formations 32 for connecting electrically conductive wires 18 to the first and second elongate members 12 and 14.

- the wire connecting formations 32 are made integrally with the first and second elongate members 12 and 14. More specifically, the wire connecting formations 32 are moulded together with the first and second elongate members 12 and 14.
- wire connecting formations 32 have been described as a pair of opposed hooks, it will be appreciated that the wire connecting formations 32 could alternatively comprise any other formation (e.g. a clipping formation) for capturing an electrically conductive wire 18 therein.
- the electrically conductive wire 18 is a bare wire, i.e. without a coating of insulating materia!.
- the adaptor 18 is similar in axial cross-sectional shape to the first and second elongate members 12 and 14. However, the adaptor 18 is shorter in axial length than the first and second elongate members 12 and 14.

- Figures 1 and 2 show the corresponding male and female connecting formations 24 and 28 on each of:
- the adaptor 18 is intended to be disposed between the first and second elongate members 12 and 14. It will be appreciated that, if the male and female connecting formations 24 and 28 on the adaptor 18 are not angularly offset, the first and second elongate members 12 and 14 will be angularly aligned. However, a 90 degree offset of the male and female connecting formations 24 and 28 on the adaptor 18 would cause the first elongate member 12 to be angularly offset relative to the second elongate member 14 by 90 degrees.

- the eiectric fence 10 and 110 offers more versatility than known electric fence systems. For instance, a variety of elongate members 12, 14, 1 12, 1 14 and 140, adaptors 18 and 1 18 and splilters 138 may be arranged in different combinations to change the configuration of the electric fence 10 and 110, Furthermore, should a user wish to extend an electric fence 10 and 1 10, it Is a simple matter of adding additional elongate members 12, 14, 1 12, 1 14 or 140 to the existing elongate members 12, 14, 1 12, 1 14 or 140,
