Abstract

The present invention relates to a sealing device comprising a sealing (1) which is threaded onto a sleeve (7), where the sleeve (7) is located in a base tube (11) comprising valve ports (12), and where the sealing device shall seal between the sleeve (7) and the base tube (11). The invention is characterized in that the sealing (1) is held in place by support rings (2), where the support rings is held in place by locking rings (3), where the lockings rings (3) fit into an inner suitable locking groove (6) in the sleeve (7), where the sleeve (7) comprises a threaded portion (8), where a locking nut (5) comprising an outer suitable locking groove (6) is arranged to be screwed over the sleeves (7) threaded portion (8) and to be tightened sufficiently to hold the locking rings (3), support rings (2) and sealing (1) in place outside the sleeve (7).
