This accommodates the body bag, and partly an inwardly directed connector, the outer dia. of which, allows the connector to be pushed through the counter ring (15). The inwardly directed connector has an outer peripheral part (14) of stretchable elastic material, inside which is a hollow space (19). This space is connected to the exterior of the fixture plate (7) by a channel (13) with a check valve (10). |
