Abstract: An assembly (10) (FIG. 1) having a passive beta port (12) and an active alpha port (14), the passive and the active are complementarily shaped such that they can engage with one another. The passive beta port (12) has an annular flange (16) defining an annular opening to which is releasably securable a passive port door (18). Disposed at the distal end of the passive (12), at the opposite end to the annular flange 16 is an annular clamp (22) having two handles (24). Disposed between the annular ring (16) and the annular clamp (22) is the gaiter (26) of the protective member (28). The protective member has a cylindrical body (30) forming a funnel through which material may pass. The free end (32) is sized so as to be capable of passing through the port formed between the alpha and beta ports (12, 14).
