An apparatus comprises a flexible pipe(12), a first connection member, a second connection member, a second auxiliary tightening unit, and a connection support unit. The flexible pipe has an annular main body with both ends having flanges. The flanges are coupled to connection flanges(46,66) of the first connection member and the second connection member. The first connection member has an upper tightening portion formed at a top of a hemispherical main body. A bolt hole is spaced apart from the upper tightening portion, and a joint hole is formed at a lower portion of the upper tightening portion so that a tie band(106) is fitted into the joint hole. A lower tightening portion is formed at a lower end of the hemispherical main body, and a bolt hole is formed at a lower portion of the lower tightening portion. The second connection member has a hemispherical main body with a top having an upper tightening portion. A bolt hole is formed at an upper portion of the upper tightening portion so that the second connection member is fixed at the bolt hole of the first connection member through a first auxiliary tightening unit and a nut. The second auxiliary tightening unit has an outer surface with a plurality of rings and an inner surface fixed at connection flanges of the first connection member and the second connection member. The connection support unit has both ends fixed at rings of the second auxiliary tightening unit, and a center which is outwardly bent.
