An apparatus (10) for visually indicating a loose wheel nut on a motor vehicle has a first means, such as a ring (12), for engaging a first wheel nut so as to be rotatable therewith and a second means, such as a ring (14), for engaging a second wheel nut adjacent to the first wheel nut so as to be rotatable therewith. The first ring (12) has a first pointer (18) for indicating a start position of the first ring (12), and the second ring (14) has a second pointer (20) for indicating a start position of the second ring (14). An elongate member (22), which is resiliently flexible, interconnects the first and second rings (12, 14). The elongate member (22) is configured to curve in at least two directions and has a first end portion (28) and an opposed second end portion (30). The first end portion (28) is connected to the first ring (12) and the second end portion (30) is connected to the second ring (14). In use, any loosening rotation of the first wheel nut will cause the first ring (12) and its pointer (18) to rotate therewith, thereby providing a visual indication of a loosening of the first wheel nut. |
