One (3a) of the projections at the ring segment (2) end has a locating surface (4a) facing the inside of the ring, with an increasing distance from the ring centre in the direction of the one end of the segment. The other (3b) projection has a locating surface (4b) facing the outside of the ring, with reducing distance from the ring centre towards one end of the segment. The two projectins (3a,3b) hold the ring segment in position in a radial direction, and the segment has at its other end a projecting lock pin (7) which can be pressed into it against the effect of a spring component (9). The ring main part (1) has at one end a recess (12) accommodating the segment lock pin in order to produce releasable locking of the segment on the main part. |
