In modified arrangement (Fig. 2, not shown) the restraining means comprises a ring (30) secured to the wheel in a manner similar to that of Fig. 1 with the hooked portions 19 being provided at circumferentially spaced locations. In a further modification (Fig. 3) each member 20 comprises two parts 40, 41, the part 41 being provided with the hooked portion 19 and being radially adjustable relative to the other part and bolt 42. In a double tyred wheel, each rim 11 is provided with a detachable bead retaining ring 10, and the restraining means comprises two retaining rings 20 and a spacer ring 60 therebetween. The rims 11, and the restraining means are clamped on wheel body 12B by lugs 57. In a modification (Fig. 5, not shown) the retaining rings 20 are integral with the spacer ring.
