<p>In a connection system (1) a second pipe (3) having a pre-formed circumferential edge, which is provided with sealing means (7), is sealingly fixed in the opening formed in a first pipe (2), whereby the pre-formed circumferential edge butts against the inner wall of the first pipe. A pipe sleeve provided with a pre-formed end, which butts against the outer wall of the first pipe, is slid over the second pipe. A nut is screwed onto screw thread formed on the other end of the second pipe, whereby the nut presses together the two pre-formed ends, between which sealing means are present. In this manner a connection between two pipes can be effected quickly without using any further fittings.</p> |
