合成樹脂チェーンにおけるリンク連結具であって、隣接する一対のリンクのピン孔に挿通される連結ピンと、リンクから突出する連結ピンの部位に嵌合される係止リングと、連結ピンと係止リングとをロックするロック部材とを備え、連結ピンと係止リングとの間は所定相対角度位置でフリーに挿入可能であるが、フリー挿入状態において連結ピンと係止リングを相対回転させることで、連結ピンと係止リングとの一方に設けた係止突起を他方に設けた係止溝に係合させて、連結ピンと係止リングとを円周方向に係止させ、ロック部材は連結ピンと係止リングとを軸線方向に相対移動せしめることで、係止突起を係止溝に係合維持せしめる合成樹脂チェーンにおけるリンク連結具。   A link connector in a synthetic resin chain, a connection pin that is inserted through a pin hole of a pair of adjacent links, a lock ring that is fitted into a portion of a link pin that protrudes from the link, a link pin, and a lock ring A locking member that locks the coupling pin and can be freely inserted between the coupling pin and the locking ring at a predetermined relative angular position. A locking projection provided on one side of the locking ring is engaged with a locking groove provided on the other side to lock the connecting pin and the locking ring in the circumferential direction, and the lock member connects the connecting pin and the locking ring. A link connector in a synthetic resin chain in which a locking projection is engaged and maintained in a locking groove by being relatively moved in the axial direction. 請求項１に記載の発明において、ロック部材はその弾性によって連結ピンとの係合状態を保持する合成樹脂チェーンにおけるリンク連結具。   2. The link connector according to claim 1, wherein the lock member retains the engagement state with the connection pin by its elasticity. 請求項２に記載の発明において、ロック部材は二股状部を有し、連結ピンを挟んで挿入される合成樹脂チェーンにおけるリンク連結具。 3. The link connector according to claim 2 , wherein the lock member has a bifurcated portion and is inserted with the connection pin interposed therebetween. 請求項３に記載の発明において、前記二股状部は先端が連結ピン外径に対し半径内方向に突出するようにされ、装着時は弾性に抗して連結ピンを乗り越えるように変形し、装着後は弾性により本来の位置に復し、連結ピンとの係合状態を保持する合成樹脂チェーンにおけるリンク連結具。 In the invention according to claim 3, the bifurcated portion has a tip projecting radially inward with respect to the outer diameter of the connecting pin, and is deformed so as to overcome the connecting pin against elasticity when mounted. The link connector in the synthetic resin chain that returns to its original position due to elasticity and maintains the engaged state with the connecting pin. 請求項３若しくは４に記載の発明において、ロック部材の二股状部の先端は先細りに形成される合成樹脂チェーンにおけるリンク連結具。 In the invention according to claim 3 or 4, the link coupling the bifurcated portions synthetic resin chain tip that will be formed on the Ri tapered locking member. 請求項１から５のいずれか一項に記載の発明において、ロック部材は抜き工具用孔を形成している合成樹脂チェーンにおけるリンク連結具。   6. A link connector in a synthetic resin chain according to claim 1, wherein the lock member forms a punch tool hole.
