TUBE JOINT

To provide a joint capable of easily inserting or pulling out a soft tube even when using the joint while connecting the tube.SOLUTION: The present invention relates to a tube joint 1 comprising an inner cylinder part 11 including a tube cover section 12 and an outer cylinder part 21 covering the tube cover section 12 of the inner cylinder part 11. The outer cylinder part 21 includes a tube lock part 22 which protrudes from an inner side face of the outer cylinder part 21 and is formed in such a manner that a protrusion height is adjustable. A tube insertion space 31 is present between the inner cylinder part 11 and the outer cylinder part 21 in the tube cover section. At least an outer side face of the inner cylinder part 11 and the inner side face of the outer cylinder part 21 in the tube cover section 12 consist of metals or hard plastics. The outer side face of the inner cylinder part 11 and the inner side face of the outer cylinder part 21 in the tube cover section 12 are entirely opposite to the insertion space 31.SELECTED DRAWING: Figure 2 【課題】軟質チューブを接続して用いる場合でも、チューブの挿入や抜き出しを容易に行うことができる継手を提供する。【解決手段】チューブ被覆区間１２を有する内筒部１１と、内筒部１１のチューブ被覆区間１２を覆う外筒部２１とを有するチューブ用継手１であって、外筒部２１は、外筒部２１の内側面から突出し、かつ突出高さが調節可能に形成されているチューブ係止部２２を有し、チューブ被覆区間において内筒部１１と外筒部２１との間にチューブの挿入空間３１が存在しており、少なくともチューブ被覆区間１２における内筒部１１の外側面と外筒部２１の内側面が金属または硬質プラスチックで構成されており、かつチューブ被覆区間１２における内筒部１１の外側面と外筒部２１の内側面が全て挿入空間３１に面している。【選択図】図２
