Claim:
1. A connection system comprising: a first connection part which defines a first passage; a second connection part connected to the first connection part when in a connected state, and which defines a second passage, the second passage being orientated with the first passage in the connected state of the connection parts, wherein the first connection part has a blunt cone section through which the first passage extends and the second connection part has a reception section having a frustoconical reception space for receiving the blunt cone section into which the second passage opens, wherein the blunt cone section seals toward a planar base of the reception space at the end face in the connected state of the connection parts; a separate sealing element disposed between a top face of the blunt cone section and the planar base; and the blunt cone section is at least partly surrounded by a sleeve and an outer side of the reception section is provided with a thread which is in friction-locking engagement with an inner surface of the sleeve in the connected state of the first and second connection parts such that an independent release of the second connection part from the first connection part is precluded.
