This invention does not make the Tip of the shell interpose into the channel of the housing and also the te, offers the connector where the aperture of the needle is possible. As for the connector of this invention, it is formed by the housing, and the elastic material where it can provide the channel and the shell joint opening it has with the needle which blocks the shell joint opening. The needle has had the fixed piece of the flange condition which projects from the peripheral face of the deformation section and the deformation section which were formed to abbreviation cylindrical condition. The deformation section, to the top panel and the top panel which are exposed from the shell joint opening has had the slit which from the base and the top panel of opposite side reaches to the base. The fixed piece is provided in the intermediate section of the top panel and the base, is locked to the housing. As for the deformation section of the needle, when the top panel the pushing is overpowered in the shell, while elasticity becoming deformed, facing to the channel, displacing, the inside which forms the slit meets to the channel, the opening which the top panel communicates to the channel is formed.本発明は、管体の先端部をハウジングの流路内に挿入させなくても、弁体の開口が可能なコネクタを提供する。本発明のコネクタは、流路と管体接続口が設けられたハウジングと、弾性材料により形成され、管体接続口を閉塞する弁体とを備えている。弁体は、略円柱状に形成された変形部と、変形部の外周面から突出するフランジ状の固定片を有している。変形部は、管体接続口から露出される天面と、天面とは反対側の底面と、天面から底面に達するスリットを有している。固定片は、天面と底面との中間部に設けられ、ハウジングに固定される。弁体の変形部は、天面が管体に押圧されると、弾性変形しながら流路へ向かって変位して、スリットを形成する内面が流路に対面し、天面が流路に連通した開口部を形成する。
