A split seal (1) having an annular cross section and a central axis (X) comprises at least two components (2, 3) of arcuate form, each component having two end portions (4, 4', 5, 5') and each end portion having a surface (F1, F2) formed and arranged for mating engagement with a respective complementary end portion surface of another of the components. Each end portion surface (F1, F2) extends in an indirect manner over one of the radial width ( delta r) and the axial length (l) of the seal and each end portion surface (F1, F2) extends substantially continuously in non-reentrant manner over the other one of the radial width ( delta r) and the axial length (l) of the seal so that the matingly engaged components are substantially smoothly, relatively translatable in one of a generally axial direction and a generally radial direction. In a preferred embodiment each end portion surface (F1, F2) extends in a zigzag manner.
