Slender tube connector

Abstract

Herein disclosed is a connector for connecting a slender tube, which comprises: a connector body and a socket member. The connector body has: a connecting portion formed at its leading end to be connected to a base; a small hole formed at its leading end; a stepped connecting bore extending therethrough and expanded from the small hole; and an annular groove formed in the inner circumference of the connecting bore. The socket member is adapted to be removably inserted into the connecting bore of the connector body at its leading end and has: a cylindrical wall for engaging with a bulging wall of the connected end of a slender tube; and a plurality of free walls arranged at a spacing at the trailing end of the cylindrical wall elastically in an expanded manner. The free walls are formed on their outer circumference with a land, which is to be fitted in the annular groove when the tube is connected, and have their trailing end expanded to the outside from the peripheral edge of the trailing end of the connector body. Further comprised is an elastic cap member which has integral inner and outer cylindrical walls extending coaxially and adapted to be fitted on the tube such that its inner cylindrical wall is clamped between the free walls and the tube whereas its outer cylindrical wall is fitted on the outer circumference of the connector body.
