PROBLEM TO BE SOLVED: To provide an inexpensive animal leash connector capable of preventing careless disconnection without addition of a component or with addition of only one easily-mountable component.SOLUTION: A lock member 12 having a cut-off part 11 is detachably mounted on the outer periphery of a base part 2 over at least its semicircle accompanied by elastic widening of the cut-off part 11 and restoration thereafter. In the mounted state, an engaging pin is locked in a closed state by preventing the retreating operation of a propping operation part in an axial direction between a hooking part 13 on the connection end side of the base part 2 and an operating part 7, and at least either is included, between a notch part 15a where a locking end side abutment part 13 which is a propping part is hooked together with a rising connecting part 7a from the engaging pin 8 of the operating part 7 in the right-left direction, and an inward projection 17 which enters a slide groove 16 allowing the rising connecting part 7a to slide in the retreating operation direction along the peripheral wall of the base part 2 and is hooked therewith in the right-left direction.COPYRIGHT: (C)2014,JPO&INPIT【課題】部品の追加無しに、あるいは簡単に装着できる1つの部品の追加を伴って連結が不用意に外れるのを防止できる低コストなものとする。【解決手段】切り離し部11を有したロック部材12は、切り離し部11の弾性的な拡幅とその後の復元を伴い基部2外まわりにその少なくとも半周を超えて着脱できるように装着され、この装着状態で、基部2の連結端側引っ掛かり部13と操作部7との間で軸線方向に突っ張り操作部の後退操作を阻止して係止ピンを閉じ状態にロックし、かつ、突っ張り部となるロック端側当接部13が操作部7の係止ピン8からの立ち上がり連結部7aと左右方向に引っ掛かり合う切り込み部15a、および、基部2の周壁に立ち上がり連結部7aを後退操作方向にスライドさせるスライド溝16に入り込んで左右方向に引っ掛かり合う内向き突起17、の少なくとも一方を備えたことにより、上記の課題を解決する。【選択図】図1
