摘要

The push-fit spacer for producing a liquid-tight connection, e.g. in a food packaging plant, comprises a tube (28) with flanges (36) at each end. Collars (130) which fit on to these have ridges (146) which cooperate with the surface of the flange and have bevelled edges (148) which allow a clamp to be attached to hold them in position.
