For indicating relative rotational displacement between a fixed first member, such as a stud (20) on a wheel hub, and a second member, such as a wheel nut (22), which is rotatably engaged with the first member, a safety device (24) comprises a body (26) having a bore formed with equispaced grooves e

For indicating relative rotational displacement between a fixed first member, such as a stud (20) on a wheel hub, and a second member, such as a wheel nut (22), which is rotatably engaged with the first member, a safety device (24) comprises a body (26) having a bore formed with equispaced grooves enabling the device to be releasably secured to the second member (22) in one position of a plurality of positions and having indicating means, such as a pointer (28), to indicate the position of the device (24) relative to a reference, such as a mark (32) on the rim (16) covering the wheel hub (14). The bore within the body (26) is closed at one end, e.g. by bevelled top wall (36), so that the body additionally serves as a dust cap for the conjoined first and second members (20, 22).

A retainer retains a wheel cover to the portion of the studs retaining a wheel to the hub of an axle, which extends beyond the lug nuts. The retainer has a metal retainer body with a planar upper and lower surface and a long end. Two arcuate portions are spaced along the long end and the metal body is beveled in the vicinity of the arcuate portions so that the arcuate portions will engage the threaded portions extending beyond the lug nuts for two adjacent studs.
