To provide an injector including an injection tube and a connector coupled thereto, and enabling a fluid supply device to be surely coupled to the connector.SOLUTION: An injector 1 is configured in such a manner that an injection tube for injecting a liquid object including a fertilized egg is coupled to a distal end side of a cylindrical connector 6, and a proximal end part 61 of the connector 6 is fitted into inside of a cylindrical part 83 for coupling, of a fluid supply device 8. A spiral groove 84 for lure lock is formed in an inner circumferential surface of cylindrical part 83 for coupling, of the fluid supply device 8, an engagement salient 63 engaged with the spiral groove 84 is formed in the proximal end part 61 of the connector 6. Therefore, by fitting the proximal end part 61 of the connector 6 into inside of cylindrical part 83 for coupling, of the fluid supply device 8, thereby engaging the engagement salient 63 with the spiral groove 84, such a situation that cylindrical part 83 for coupling, of the fluid supply device 8 is detached from the proximal end part 61 of the connector 6 hardly occurs. The connector 6 is formed of a transparent resin.SELECTED DRAWING: Figure 4 【課題】注入管に連結したコネクタに流体供給器を確実に連結することのできる注入器を提供すること。【解決手段】注入器１では、受精卵等を含む液状物を注入するための注入管が筒状のコネクタ６の先端側に連結され、コネクタ６の基端部６１は、流体供給器８の連結用筒部８３の内側に嵌められる。流体供給器８の連結用筒部８３の内周面には、ルアーロック用の螺旋溝８４が形成され、コネクタ６の基端部６１には、螺旋溝８４と係合する係合凸部６３が形成されている。従って、流体供給器８の連結用筒部８３の内側にコネクタ６の基端部６１を嵌めて、螺旋溝８４に係合凸部６３を係合させれば、コネクタ６の基端部６１から流体供給器８の連結用筒部８３が抜けるという事態が発生しにくい。コネクタ６は透明な樹脂製である。【選択図】図４
