Abstract

A pipe connection joint which is repeatedly usable when an analysis column is replaced with another in a liquid chromatographic device. To this end, an elastic body is built into a compression screw for inserting a pipe passed through a ferrule into the analysis column to thereby axially movably support the pipe, and a pipe clamp is secured in advance at a predetermined position of the pipe. A distance between the ferrule and the pipe clamp changes on the basis of the length of a portion of the pipe sticking out from the ferrule and the pressing force of the elastic body applied to the pipe.
