A device (1) for providing a fixing point for an insulated glass unit (3), the device having clamping blocks (22) to mount the device (1) though opposed panes of glass (5, 6) of the unit (3) and a spacer (10) with opposed faces (13, 14). At least one of the opposed faces (13, 14) having an annular groove (17, 18) for carrying sealant to seal against an associated one of the glass panes (5, 6) when the glass panes (5, 6) are tensioned together by the clamping blocks (22).

1. A device for providing a fixing point for an insulated glass unit, the device having clamping blocks to mount the device in holes provided in opposed panes of glass of the unit and a unitary spacer with a bore through which the clamping blocks are connected, the spacer having opposed faces provided with an annular groove for carrying sealant to seal against an associated one of the glass panes when the glass panes are tensioned together by the clamping blocks, wherein the spacer includes a flange to locate the spacer in one of the holes and wherein the spacer provides a solid unitary body that extends from the bore through to a periphery thereof and the annular grooves are in the form of wells recessed into opposed sides of the body and adapted to receive the sealant prior to the spacer being fitted between the panes of glass, wherein the clamping blocks are coupled together by a threaded coupling which passes through the unit, the threaded coupling having a pair of opposing stop devices, each of the opposing stop devices being formed on opposing ends of the threaded coupling, one of the opposing stop devices comprising an annular shoulder stop protruding outwardly from one end of the threaded coupling, and the other one of the opposing stop devices comprising an annular end stop protruding inwardly from the opposing end of the threaded coupling, wherein each of the clamping blocks carries a seal to engage with the opposed panes of glass. 2. The device of claim 1, wherein the flange is an integral annular flange which projects axially of one of the faces of the spacer. 3. The device of claim 2, wherein an end of the flange is beveled to facilitate easy insertion in the hole. 4. The device of claim 2, wherein the spacer includes a second annular flange projecting axially of the other one of the faces so as to locate in the other one of the holes. 5. The device of claim 1, wherein the clamping blocks are formed of two nuts, arranged to be screw threaded onto an axle which extends therebetween, through the glass unit. 6. The device of claim 1, incorporating the sealant which is formed of polyisobutylene material. 7. The device of claim 6, wherein the sealant is filled in the annular groove to a depth at least as deep as the annular groove. 8. The device of claim 1, wherein one of the clamping blocks is adapted to carry a stem for mounting the glass unit to a supporting structure. 9. The device of claim 8, wherein the stem is removable to allow the glass unit to be flat packed. 10. The device of claim 1, wherein the spacer provides a solid unitary body that extends from the bore through to a periphery thereof and the annular grooves are in the form of wells recessed into opposed sides of the body and adapted to receive the sealant prior to the spacer being fitted and clamped between the panes of glass such that no additional sealant material is needed to seal between the spacer and the glass panes. 11. A spacer for use in the device of claim 1, the spacer being formed as a unitary structure with a flattened donut shape, with annular grooves formed on opposed faces thereof, and an integrally formed flange to locate the spacer in a corresponding hole formed in a pane of glass, wherein the spacer provides a solid unitary body that extends from the bore through to a periphery thereof and the annular grooves are in the form of wells recessed into opposed sides of the body and adapted to receive the sealant prior to the spacer being fitted between the panes of glass. 12. The spacer of claim 11, wherein the flange projects axially of one of the faces of the spacer. 13. The spacer of claim 12, wherein an end of the flange is bevelled to facilitate easy insertion in a hole of a pane of glass of an integrated glass unit. 14. The spacer of claim 11, further including a second annular flange projecting axially of the other one of the faces. 15. The spacer of claim 11, wherein the spacer provides a solid unitary body that extends from the bore through to a periphery thereof and the annular grooves are in the form of wells recessed into opposed sides of the body and adapted to receive the sealant prior to the spacer being fitted and clamped between the panes of glass such that no additional sealant material is needed to seal between the spacer and the glass panes. 16. A clamping block structure for an insulated glass unit, including clamping blocks sealed on opposed panes of glass, wherein the clamping blocks are coupled together by a threaded coupling which passes through the unit, the threaded coupling having a pair of opposing stop devices to inhibit over tensioning of the panes of glass clamped between the clamping blocks, each of the opposing stop devices being formed on opposing ends of the threaded coupling, one of the opposing stop devices comprising an annular shoulder stop protruding outwardly from one end of the threaded coupling, and the other one of the opposing stop devices comprising an annular end stop protruding inwardly from the opposing end of the threaded coupling, wherein each of the clamping blocks carries a seal to engage with the opposed panes of glass. 17. The clamping block structure of claim 16, wherein the clamping block structure is adapted to couple to a device for providing a fixing point for an insulated glass unit, the clamping blocks adapted to mount the device holes provided in opposed panes of glass, the clamping blocks adapted to tension together the glass panes.
