1. A filter insert comprising: a body portion and a closed-ended tube, an open end of which is sealingly affixed around the periphery of the body portion; an inlet aperture and an outlet aperture each aperture communicating via a through hole in the body portion with the interior of the tube; a filter medium located within the tube and being sealingly interposed between the inlet aperture and the outlet aperture, wherein the tube comprises an impermeable barrier and at least partially manufactured of a flexible plastics material, wherein the flexible material comprises plastics film, wherein the plastics film is provided with a metallised surface coating on one or both sides thereof, and wherein the body portion is rigid relative to the tube. 2. A filter insert as claimed in claim 1, wherein the plastics film comprises a food-grade polymer film. 3. A filter insert as claimed in claim 1, wherein the plastics film comprises a laminated plastics film. 4. A filter insert as claimed in claim 3, wherein the laminated film comprises at least one or more of the layers comprising: polyethylene; aluminium; polyamide; and polyethylene terephthalate. 5. A filter insert as claimed in claim 1, wherein the body portion comprises a mounting disc. 6. A filter insert as claimed in claim 1, further comprising a reinforcing disc located, in use, adjacent the body portion for inhibiting and/or preventing deformation of the body portion. 7. A filter insert as claimed in claim 1, further comprising inlet and outlet spigots that extend radially from an outer surface of the body portion and wherein the inlet and outlet apertures communicate respectively with the inlet and outlet spigots. 8. A filter insert as claimed in claim 1, wherein the filter medium comprises a porous material. 9. A filter insert as claimed in claim 8, wherein the porous material comprises compressed and/or sintered activated carbon. 10. A filter insert as claimed in claim 8, wherein the porous material comprises resin. 11. A filter insert as claimed in claim 8, wherein the filter medium is tubular. 12. A filter insert as claimed in claim 11, wherein the direction of flow of fluid from the inlet aperture to the outlet aperture of the filter insert is radially inwardly from the exterior of the tube towards the interior of the tube. 13. A filter comprising a connector, a housing detachably affixable to the connector and a filter insert removably receivable in the housing; the connector comprising an inlet and outlet apertures for connection to a supply of fluid and fluid-consuming device, respectively; the filter insert comprising an inlet and outlet apertures releasably and sealingly connectable to the inlet and outlet apertures of the connector, a filter medium sealingly interposed between the connected inlet and outlet apertures and a substantially fluid impermeable barrier surrounding the insert and being arranged to prevent the fluid from coming into contact with the housing, the filter further comprising a locking collar that comprises a lug adapted to engage with an engagement surface of at least one of the housing, connector and collar, the engagement surface comprising a first flat portion and an inclined portion, wherein relative rotation of the collar and connector in a first direction causes the lug to slide over the first flat portion, thereby inhibiting axial separation of the housing and connector, and then over the inclined portion, thereby displacing the housing axially towards the connector, and wherein relative rotation of the collar and connector in a second direction opposite to the first direction causes the lug to slide over the inclined portion, thereby allowing the housing to be displaced axially away from the connector, and then over the first flat portion thereby inhibiting axial separation of the housing and connector. 14. A filter as claimed claim 13, wherein the substantially fluid impermeable barrier is relatively flexible and wherein the housing is relatively rigid and is arranged to mechanically support the substantially water impermeable barrier. 15. A filter as claimed in claim 13, wherein the radial clearance between the exterior of the filter insert and the interior of the housing is any one or more of the group comprising: less than 1mm; less than 0.5mm; and less than 0.25mm. 16. A filter as claimed in claim 13, further comprising a locking collar for releasably locking the housing to the connector. 17. A filter as claimed in claim 13, wherein the interior of the housing comprises engagement means for engaging and/or supporting the filter medium of the filter insert. 18. A filter as claimed in claim 13, further comprising a flow control valve associated with one or both of the inlet and outlet apertures. 19. A filter as claimed in claim 13, further comprising an o-ring seal interposed between the connector and the housing. 20. A filter as claimed claim 13, wherein the housing comprises a transparent portion. 21. A filter as claimed in claim 13, further comprising a clip comprising a releasable securement portion to releasably secure the connector to a surface. 22. A filter as claimed in claim 21, wherein the releasable securement portion comprises a generally U-shaped clip whose resiliently deformable arms are resiliently deformable into engagement with an exterior wall of the connector.
