A sealing element 18, 26 for locating an annular seal plate 8 in an annular recess 14,16 is in the form of a ring or a segment of a ring and comprises a channel around its circumference, the mouth 24 of which receives the seal plate 8. The sealing element 18, 26 is thus fitted between the seal plate 8 and the recess 14, 16 in a housing member 2, 4 and can protect the housing member against wear caused by the movement of the seal plate 8. Generally, such sealing elements 18, 26 will be used to seal a gap 6 between two housing parts 2, 4 for example in a gas turbine. The sealing elements 18, 26 may have radially inwards and outwards facing channels for receiving respectively the outer and inner edges of a generally annular sealing plate 8. Alternatively the sealing elements 18, 26 may have axially facing channels for receiving the edges of a generally cylindrical sealing plate 8.
