<p>The present invention relates to a tube holder and a tube connection device using the same. The tube holder (10) is used to firmly fixate a tube (50) on a tube connection part (31) in a pressure sensor. When a holder body (11) is rotated in a state where a passage (32) of the tube connection part (31) is inserted in the tube (50), the holder body and the tube connection part are coupled by a fastening screw part (16) of the holder body (11) and a coupling screw part (37) of the tube connection part (31). A part of the tube (50) is positioned between a contact protrusion (16) formed on the inner surface of the holder body (11), and a compression protrusion (34) formed on the middle of the passage (32) to be compressed. The more the holder body (11) is rotated, the more the coupled state becomes firm; when a rotation locking part (20) of the tube holder (10) is inserted and hung on a locked part (40) of the tube connection part (31), the rotation of the holder body (11) is shut off to lock the coupled state. Accordingly, the passage formed by connecting the tube (50) and the tube connection part (31) is closed, and the connected state of the tube (50) and the tube connection part (31) becomes firm.</p> |
