A piggy back pipeline arrangement in which a saddle (4, 24) is interposed between two pipelines (2, 22) which are then clamped together: the saddle has a bushing means (12, 32). The bushing means is securable to the saddle and at least partly encircles a smaller (3, 23) of the two pipelines. After fitting the bushing means is closed round the smaller pipeline and when the pipelines are strapped together the arrangement relieves stress and helps to prevent the displacement of the strapping. <IMAGE> |
