PURPOSE: To take up a connecting part of an arbitrary size, and to prevent the sticking of a needle simultaneously, by installing a canula movably between a pair of fingers on a base, and making the fingers warped inside corresponding to the movement of a collar installed between a backspace position of the canula and the take-up position of the connecting part of the primary tube. CONSTITUTION: The primary tube comprises a connecting part 8 having a partitioning wall 9, and the secondary tube 10 is connected with the primary tube 4 by a connector 12. An element to be held 22 comprises a hub 24, a base 26, and a pair of fingers 32, 34 integrally, the base 26 comprises an internal passage 28 through which a needle 30 is passed, and the fingers 32, 34 respectively comprise the distal ends 58, 60, which are connected with the base 26 through the connecting parts 62, 64 to be used as the friable part. And a passage 56 and a through hole in the needle 30 are used as a tube passage. The fingers 32, 24 demarcate the internal space part 36 through which the needle 30 is penetrated and extended, thereby an user can be prevented from carelessly sticked by the needle.
