초록 ▼

A plug connection for aquarium pressure medium conduits, particularly in combination with external aquarium filter devices. The connection comprises a plug, and a sleeve for receiving the plug. Both the plug and the sleeve are provided with a valve disc capable of blocking an associated conduit. Each valve disc is liftable from a sealing seat thereof against the force or biasing effect of a spring associated therewith. During plugging together of the plug and sleeve, axially displaceable shafts of the valve discs come into abutment with each other. The housing of the plug and the housing of the sleeve are capable of being plugged together in such a manner that a pressure-tight conduit is formed between the two valve discs.
