A pivot joint (1) comprises a first member (2) of generally channel section with diverging walls (4) at least in the region of the joint (1), a second member (3) to which the first member (2) is to be pivotally connected and which is adapted to lie at least partially within the first member (2) in the region of the joint (1) and which has divergent sides (5) in the same sense as the first member (2), at least in the region of the joint (1) and a joint body (10) of channel shape with substantially parallel sides (14,15) prior to assembly. First attachment means (6) are provided on the first member (2) for cooperation with first attachment means (11) on the joint body (10) and second attachment means (7) are provided on the second member (3) for cooperation with second attachment means (12) on the joint body (10). The arrangement is such that when the joint body (10) is pushed into the first member (2) and onto the second member (3), the parallel sides (14,15) of the joint body (10) are splayed outwardly and engagement between the first attachment means (6, 11) and the second attachment means (7,12) is achieved, at least one of the attachment means (6,7,11,12) being so constructed as to allow at least limited pivotal motion between the associated member (2,3) and the joint body (10). The invention also includes a method of making such a joint. |
