The invention claimed is: 1. An arrangement for mounting a non-rotating component of a gas turbine engine, defining a portion of a gas path of the gas turbine engine, comprising: a non-rotating component having structure defining a receptacle, the receptacle having an opening; and a fastener for retaining the non-rotating component, comprising a neck portion and a head portion, wherein the neck portion of the fastener extends through the opening and the head portion is retained, at least partially, within the receptacle wherein the receptacle is defined by at least two opposing sidewalls converging towards the opening. 2. An arrangement as claimed in claim 1, wherein the gas turbine engine comprises a casing, and the fastener fastens the non-rotating component to a portion of the casing of the gas turbine engine. 3. An arrangement as claimed in claim 2, wherein the fastener extends through the casing. 4. An arrangement as claimed in claim 2, wherein the head portion of the fastener comprises a surface that, in use, abuts the casing of the gas turbine engine. 5. An arrangement as claimed in claim 1, wherein the head portion of the fastener has a dovetail shape. 6. An arrangement as claimed in claim 1, wherein the fastener provides a tenon of a tenon and mortise combination for retaining the non-rotating component. 7. An arrangement as claimed in claim 1, wherein the neck portion of the fastener comprises an interference collar. 8. An arrangement for mounting a non-rotating component, defining a portion of a gas path, of a gas turbine engine, having an axis, comprising: a removable fastener for retaining a non-rotating component in at least a first direction, when the engine is in use, and in at least a second, different direction, when the engine is not in use wherein the second direction is radial, relative to the axis of the gas turbine engine. 9. An arrangement as claimed in claim 8, wherein the first direction is circumferential, relative to the axis of the gas turbine engine. 10. An arrangement as claimed in claim 8, wherein the removable fastener comprises a head portion and the non-rotating component comprises a receptacle for receiving and retaining, at least partially, the head portion. 11. An arrangement as claimed in claim 8, further comprising a first support for retaining the non-rotating component in the second direction, wherein the first support is a hook or a flange that abuts the casing of the gas turbine engine. 12. An arrangement as claimed in claim 8, further comprising a second support for retaining the non-rotating component in a third direction, wherein the second support is a retaining ring. 13. An arrangement as claimed in claim 8, wherein the non-rotating component is a nozzle guide vane of a gas turbine engine or a shroud segment of a gas turbine engine.
