Abstract: An attachment means (4) in the form of a hollow cylindrical socket (10) integral with a tangentially intersecting housing (30) in which a latch pin (8) is longitudinally slidable. The latch pin (8) has a cylindrical head (8a) of relatively large diameter but relatively short length, and a cylindrical shaft (8b) that is relatively long but of relatively small diameter. The axis of the latch housing is offset outwardly of an imaginary line tangentially intersecting the bore of the socket by more than half the diameter of the latch pin shaft (8b) but less than half the diameter of the latch pin head (8b). The latch pin (8) is biased by a spring (7) such that the latch pin head (8a) normally lies partly within the bore of the socket (10) to engage a notch (12) near the end of a rod (5) or other plug-like member attached to the socket (10) and thereby positively retain this rod (5).

Abstract: A mudguard assembly for heavy goods vehicles. A moulded mudguard, sized to envelop more than 50% of the upper part and rear of an outer tyre of the vehicle is mounted on two rods engageable in sockets bolted to the chassis of the vehicle. The assembly includes a quick release mechanism to enable ease of installation and of removal of the mudguard for access.
