ABSTRACT:
A syringe is provided with a Luer-Lok portion for connecting an extension tube or the like. The Luer-Lok portion is arranged upright on a plane of truncation of a conical-frustum-shaped free end portion of the syringe, and includes an inner cylindrical portion and an outer cylindrical portion surrounding the inner cylindrical portion and having at least two projecting helical ribs formed in parallel with each other on an inner peripheral surface thereof. The extension tube or the like can be connected to the Luer-Lok portion by screwing at least two projecting helical ribs of a cylindrical connector, said at least two projecting helical ribs being formed in parallel with each other on an outer peripheral surface of the cylindrical connector, in corresponding grooves defined between the helical projecting ribs of the outer cylindrical portion. A lower end portion of at least one of the projecting helical ribs of the Luer-Lok portion is formed at a position higher than an upper surface of a bottom wall between both of the cylindrical portions.
