Protective device, protective arrangement for a container and method for connecting a protective device to a container

A protective device for a container for receiving substances, wherein—the protective device o comprises a flexible casing that surrounds a casing space and comprises a first casing opening and a second casing opening;

• has a first tubular member connected to the casing in the region of the first casing opening and having a first container counter-connector unit,
• a primary first end, and a primary second end, and
• has a second tubular member connected to the casing in the region of the second casing opening and having a second container counter-connector unit, a secondary first end, and a secondary second end, wherein—the first tubular member is connected to the casing such that the primary first end terminates with the first casing opening or projects into the casing space,
• the second tubular member is connected to the casing such that the secondary first end terminates with the second casing opening or projects into the casing space;
• and
• the protective device is connectable to a first container connector unit that surrounds a first container opening of said container and by which the first tubular member is connectable to the container by means of the first container counter-connector unit such that the casing can be introduced into an inner space surrounded by a wall of the container, and
• connectable to a second container connector unit that surrounds a second container opening of said container and by which the second tubular member is connectable to the container by means of the second container counter-connector unit such that the casing can be introduced into the inner space surrounded by the wall of the container, and wherein—a first coupling unit is arranged at the primary second end of the first tubular member to connect a connector member,
• a second coupling unit is arranged at the secondary second end of the second tubular member to connect a connector member,
• the first coupling unit being formed in the manner of a first tri-clamp connector and the second coupling unit is formed in the manner of a second tri-clamp connector.
