PROBLEM TO BE SOLVED: To provide a suction connector the suction force of which can be adjusted sufficiently through negative pressure opening and which can surely prevent the scattering of a fluid and, accordingly, an operator from being contaminated and infected and has a simple structure. SOLUTION: The suction connector is provided with a fluid passage 31 one end of which is connected to a conduit and the other end of which is connected to a suction source when the connector is used and a ventilation path 32 which is branched from the middle of the passage 31 and has an opened end 33. In at least a partial area in the path 32 on the fluid passage 31 side, blocking plates 34 which divide the cross section of the path 32 into a plurality of areas are arranged so as to prevent the fluid entering the path 32 from the passage 31 from flowing out of the opened end 33.
