consolidated, is likely to work in the connection release, moreover, due to the complication, also not due to the complication, connecting device for low suppressed are animals that the probability that the work is inadvertent uncoupling the operation unit to provide. connector 200 includes a body 4 which forms the bifurcated portion 3 to the distal end portion 10 side that extends from the base 2 to the base ring 1 is connected, to open and close the opening portion 5 of the forked portion 3 forked portion in cooperation with the consolidation of the consolidated 6 and, and an opening and closing mechanism 7 for connection release, opening and closing mechanism 7, the opening and closing member 8, which moves back and forth to open and close between the open portion 5 one side 3a and the other side 3b of the, spring 9 biases so as to close the opening and closing member 8, and, to to the arrangement surface 4a which is lined forked portion 3 of the body, the closing operation to advance from one side 3a of the bifurcated portion 3 on the other side 3b of the opening and closing member 8 operation unit 21 is moved to one side 3a of the arrangement direction of the other side 3b of the forked portion 3 in response, whereas from the side 3a is operated to the other side 3b opening the closing member 8 is moved backward against the spring 9, the has, to achieve the above object.連結、連結解除の作業がしやすく、しかも、拗れに起因して、また拗れに起因しないで、操作部に不用意な連結解除が働く確率を低く抑えられる動物用の連結具を提供する。 連結具200は、基部環1が連結された基部2から延びた先端部10側に二股部3を形成している本体4と、二股部3の開放部5を開閉し二股部と協働して連結対象6を連結、連結解除する開閉機構7とを備え、開閉機構7は、開放部5を一方側3aと他方側3bとの間で進退して開閉する開閉部材8、開閉部材8を閉じるように付勢するばね9、および、本体の二股部3が並ぶ並び面4aに臨出して、開閉部材8の二股部3の一方側3aから他方側3bに進出する閉じ動作に応動して二股部3の並び方向の他方側3bから一方側3aに移動され、一方側3aから他方側3bに操作されて開閉部材8をばね9に抗し後退させて開く操作部21、を有して、上記の目的を達成する。
