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 ( 8 a) of relatively large diameter but relatively short length, and a cylindrical shaft ( 8 b) 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 ( 8 b) but less than half the diameter of the latch pin head ( 8 b). The latch pin ( 8 ) is biased by a spring ( 7 ) such that the latch pin head ( 8 a) 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 ). Manually depressing the latch pin ( 8 ) against the force of the spring ( 7 ) pushes the latch pin head ( 8 a) out of the bore of the socket ( 10 ) which instantly releases the rod ( 5 ) since the latch pin shaft ( 8 b) always lies completely outside the bore of the socket ( 10 ). The attachment assembly ( 4+5 ) allows easy assembly of two members, and their quick release when required. The attachment means is applicable to attachment of parts and accessories to vehicles, e.g. mudguards ( 14 ) and side-skirts ( 50, 51 ).
