PROBLEM TO BE SOLVED: To provide a lock type splicer capable of securely preventing screwing using lock means from being loosened.SOLUTION: A lock type splicer comprises: a male connector 10 including a connection insertion part 11 formed at the tip of the male connector a female connector 14 that includes a fitting part 14c capable of fitting the connection insertion part 11 by making the connection insertion part be inserted into the fitting part, is connected to the male connector 10 by the connection insertion part 11 fitting into the fitting part 14c to be made to be capable of circulating liquid, and includes a male screw part 14b formed on the outer peripheral surface and lock means 12 that is mounted on the male connector 10 and includes a female screw part 12a capable of being screwed on the male screw part 14b, the female screw part being formed on the inner periphery surface. A convex shape 13 is formed on the male connector 10 the lock means 12 has a concave shape 12ba transferred by the convex shape 13 being pressed. Fitting the convex shape 13 on the concave shape 12ba prevents the lock means 12 from being loosened.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】ロック手段による螺合の緩みを確実に防止することができるロック式接続具を提供する。【解決手段】先端部に接続挿入部11が形成されたオスコネクタ10と、接続挿入部11を挿入させて嵌合可能な嵌合部14cを有し、当該嵌合部14cに対する接続挿入部11の嵌合によりオスコネクタ10と接続されて液体を流通可能とされるとともに、外周面に雄ネジ部14bが形成されたメスコネクタ14と、オスコネクタ10に取り付けられるとともに、内周面に雄ネジ部14bと螺合可能な雌ネジ部12aが形成されたロック手段12とを具備したロック式接続具において、オスコネクタ10には凸形状13が形成されるとともに、ロック手段12には凸形状13が押圧されることによって転写された凹形状12baを有し、当該凸形状13及び凹形状12baが嵌合してロック手段12が緩み止めされるものである。【選択図】図2
