Abstract: A fluid connector is provided which is especially adapted for use with low-pressure fluids. The fluid connector comprises a bored mobile joint possessing an internal chamber communicating with a tubular conduit and upper and lower coaxial, opposed bore-holes whose common axis is substantially perpendicular to said tubular conduit. A screw brace is inserted into said bore-holes. The leg portion of the screw brace possesses an internal conduit which is co-axial with the common axis of the bore-holes and which communicates with the internal chamber, said leg portion further possessing upper and lower annular grooves and a threaded portion starting below the lower annular groove. A metallic retaining ring is positioned below the upper bore-hole and is disposed within the upper annular groove.
