A connector for a container, particularly a cask, comprises a bush (14), intended to be received in an opening (11) in the container through which liquid is discharged, in use. The bush has a closed end (17) with a weakened portion (18), an inner thread (20) and an inner deformable portion (21). Sealing means (23) are intended to be disposed between the exterior of the bush and the interior of the opening at the position of the deformable portion. An insert (15) is screw-threadedly engageable within the bush so as to deform the deformable portion, thereby effecting compression, and thus sealing, of the sealing means between the bush and the container.

1. A connector for a container, particularly a cask, comprising a bush, received in an opening in the container through which liquid is discharged, in use, the opening having an interior, the bush having an exterior, an interior and a closed end with a weakened portion, an inner thread and an inner deformable portion disposed at a position of the bush, sealing means disposed between the exterior of the bush and the interior of said opening at said position of the bush, and an insert screw-threadedly engageable within said bush so as to deform said deformable portion, thereby effecting compression, and thus sealing, of said sealing means between said bush and the container. 2. A connector according to claim 1, also comprising a further insert which is screw-threadedly engageable within said insert to a position where cutting means of said further insert cut through said weakened portion of the closed end of the bush to provide an opening from the container for liquid to discharge through the further insert. 3. A connector according to claim 2, wherein said further insert is a broach. 4. A connector according to claim 1, wherein the closed end of the bush is defined by a membrane, preferably integral. 5. A connector according to claim 2, wherein the closed end comprises a membrane having a center part and an annulus, the annulus forming the weakened portion, and the weakening allows the center part of the membrane to be cut out by the cutting means of the further insert. 6. A connector according to claim 1 wherein the bush carries an O-ring at its exterior, forming said sealing means. 7. A connector according to claim 1, wherein the bush has an open end defining an open perimeter of the bush, the bush being formed with a number of slots therearound, each extending from said open end to allow the open perimeter part of the bush to move outwardly to form a taper matching an internal taper of the opening in the container. 8. A connector according to claim 7, wherein the bush has an internal tapered female thread and the insert has a tapered male thread on its exterior surface to engage said tapered female thread to spread the slots of the bush. 9. A connector according to claim 1 wherein the interior of the bush adjacent the closed end of the bush has a dilating annulus constituting said deformable portion. 10. A connector according to claim 1, wherein the insert is a dilator. 11. A connector according to claim 3, wherein the insert has an interior formed with a parallel thread to match an exterior thread of the further insert. 12. A connector according to claim 3, wherein the broach is a hollow tube with cutting spikes on its leading end. 13. A connector according to claim 2, wherein the insert has an interior formed with a parallel thread to match an exterior thread of the further insert, wherein the insert is a hollow tube with cutting spikes on its leading end. 14. A method of fitting a connector to an opening in container, particularly a cask, through liquid is discharged, in use, wherein the connector comprises a bush having a closed end and a weakened portion, an inner thread and an inner deformable portion disposed at a position of the bush, sealing means, and an insert screw-threadedly engageable within said bush, the method comprising positioning said bush in said opening with said sealing means disposed around said bush at said position, and threadedly engaging said insert into said bush so that it deforms said inner deformable portion thereby effecting compression, and thus sealing of said sealing means between said bush and the container. 15. A method according to claim 14, further comprising threadedly engaging into said insert a further insert such that cutting means of said further insert cut through said weakened portion of the bush to provide an opening from the container for discharge of liquid through said further insert. 16. A connector for a container, particularly a cask, comprising a bush, received in an opening in the container through which liquid is discharged, in use, the opening having an interior, the bush having an exterior, a closed end with a weakened portion, an inner thread and an inner deformable portion disposed at a position of the bush, sealing means disposed between the exterior of the bush and the interior of said opening at said position, and an insert screw-threadedly engageable within said bush so as to deform said deformable portion, thereby effecting compression, and thus sealing, of said sealing means between said bush and the container, the connector also comprising a further insert which is screw-threadedly engageable within said insert to a position where cutting means of said further insert cut through said weakened portion of the closed end of the bush to provide an opening from the container for liquid to discharge through the further insert and wherein the weakened portion is an annulus, the closed end comprising a membrane having a center part and the weakening allowing the center part of the membrane to be cut out by the cutting means of the further insert.
