a third portion ( 26 ) partially defining at least one said second aperture and adapted to be mounted to said first portion and said second portion when at least one said first cable is retained in a respective said first aperture, to cause at least one said second cable to be retained in a respective said second aperture, wherein said first portion comprises at least one support ( 30 ) adapted to be mounted to said second portion, and at least one first body portion ( 34 ) partially defining at least one said first aperture, wherein said first body portion is adapted to be mounted to said second portion, wherein said second portion comprises a second mounting part ( 42 ) for mounting said second portion to at least one said support, and wherein said second mounting part ( 42 ) comprises at least one protrusion ( 44 ) or recess adapted to engage a respective recess ( 46 ) or protrusion on said support, and a retaining device ( 48 ) for retaining said first and second portions in position relative to each other, such that engagement of at least one said protrusion or recess with the corresponding recess or protrusion prevents electrical conduction from a said first cable to said retaining device.

8. An apparatus according to claim 7 , wherein said retaining device engages at least one recess in said second portion.

9. An apparatus according to claim 7 , further comprising at least one insert comprising a plurality of body members ( 124 ) adapted to be mounted to each other to define a said second aperture ( 126 ) for receiving a cable, wherein each said body member comprises an engaging device ( 128 ) adapted to engage a corresponding engaging device ( 130 ) on a further said body member to prevent electrical conduction from a cable received in the second aperture to a body of the cable retaining apparatus.

10. An apparatus according to claim 9 , wherein the engaging device comprises at least one protrusion ( 132 ) and/or first recess ( 134 ) adapted to engage a corresponding first recess and/or protrusion on a further said body member.

11. An apparatus according to claim 9 , further comprising at least one flange portion ( 136 ) extending from a respective end portion ( 138 ) of the body member.

12. An apparatus according to claim 9 , wherein at least one said body member defines a respective second recess ( 140 ) for receiving an elongate member arranged adjacent a said cable.

13. A cable retaining apparatus ( 10 ) comprising:

a first portion ( 12 ) partially defining at least one first aperture ( 14 ) for receiving a respective first cable;

a second portion ( 18 ) partially defining at least one said first aperture, and partially defining at least one second aperture ( 22 ) for receiving a respective second cable, wherein said second portion is adapted to be mounted to said first portion to cause at least one said first cable to be retained in a respective said first aperture, wherein said second portion comprises a plurality of second body portions ( 50 ), each of which is adapted to retain a respective said first cable in the corresponding said first aperture, wherein at least one said second body portion comprises a profiled portion ( 52 ) adapted to engage a corresponding profiled portion on a further said second body portion; and

a third portion ( 26 ) partially defining at least one said second aperture and adapted to be mounted to said first portion and said second portion when at least one said first cable is retained in a respective said first aperture, to cause at least one said second cable to be retained in a respective said second aperture.
