I claim: 1. A securing assembly comprising: a first rotatable member defining a first recess, and a second rotatable member defining a second recess, the second recess having an engagement formation, securing means rotatable in the first and second recesses for securing the first and second rotatable members to each other, and an urging formation provided on at least one of the securing means and the first rotatable member for urging the securing means into engagement with the engagement formation when the first and second rotatable members are rotated, comprising an urging wall of the first recess, the urging wall being angled relative to the axis of rotation of the first and second rotatable members to effect the aforesaid urging of the securing means. 2. A securing arrangement according to claim 1, wherein the engagement formation comprises an engagement wall. 3. A securing arrangement according to claim 1, wherein an urging formation is provided on the securing means. 4. A securing arrangement according to claim 3, wherein the urging formation on the securing means comprises an urging wall, chamfered relative to the axis of rotation of the first and second rotatable members. 5. A securing arrangement according to claim 4, wherein the urging wall of the recess and the urging wall of the securing means define the same angle relative to the axis of rotation. 6. A securing arrangement according to claim 5, wherein the urging walls face each other and the urging wall of the recess faces inwardly of the recess. 7. A securing arrangement according to claim 1, wherein the first and second rotatable members each comprises first and second recess defining portions to define the first and second recesses, the first and second recess defining portions extending through at least an arc of a circle. 8. A securing arrangement according to claim 7, wherein at least one of the first and second recess defining portions is generally annular. 9. A securing arrangement according to claim 8, wherein both of the first and second recess defining portions are annular. 10. A securing arrangement according to claim 7, wherein the first recess defining portions of each rotatable member comprise external walls, wherein the external walls define respective re-entrant formations which when aligned with each other provide an opening to enable the securing means to be located within the recess. 11. A securing arrangement according to claim 1, wherein the first and second recesses are aligned with each other to define an internal channel when the securing means is received therein. 12. A securing arrangement according to claim 1, wherein the securing means includes at least one securing member, locatable in the first and second recesses. 13. A securing arrangement according to claim 12, wherein the at least one securing member is slidable into the first and second recesses. 14. A securing arrangement according to claim 13, wherein a pair of said securing members are locatable in general co-axial alignment with each other in the recesses. 15. A securing arrangement according to claim 14, wherein each securing member comprises a half ring. 16. A securing arrangement according to claim 15, wherein two pairs of securing members arranged opposite to each other around an annulus, wherein securing members of each pair are arranged co-axially of each other, and each securing member extends generally around a semi-circle of the annulus. 17. A securing arrangement according to claim 14, wherein each securing member is annular in configuration, and each has a break therein. 18. A securing arrangement according to claim 17, wherein the break extends radially across the securing member. 19. A securing arrangement according to claim 18, wherein each securing member comprises a split ring. 20. A securing arrangement according to claim 12, wherein the securing member is annular in configuration, and comprises a spiralled elongate member comprising a first portion overlapping a second portion. 21. A securing arrangement according to claim 20, wherein the securing member comprises a spiral member having generally two full turns, wherein each turn engages an adjacent turn. 22. A securing arrangement according to claim 12, wherein the securing members are slidable into the recesses. 23. A rotary component of a gas turbine engine incorporating a securing assembly according to claim 1. 24. A rotary component according to claim 23 comprising a turbine. 25. A gas turbine engine incorporating a rotary component according to claim 23.
