To prevent inconvenience that an opened gas cock is closed by mischief or wrong operation, and reduce the number of components to enable installation in a compact manner without obstruction or interference around a pipe, in a wrong operation prevention tool comprising a pipe connection cylinder part (21) and an operation handle (20) from which a lever part (25) projects, wherein when a gas cock (2) is in an open state, the lever part (25) is mounted to the gas cock positioned along the pipe connection cylinder part (21).SOLUTION: A locking part (10) lockable to a lever part (25), and a leg part (11) lockable to at least a part of an outer peripheral surface of a pipe connection cylinder part (21) in an externally fitted manner are provided in one prevention tool body (1). Only when a gas flow passage is in an open state, the locking part (10) and the leg part (11) are configured to be respectively lockable to the lever part (25) and the pipe connection cylinder part (21) simultaneously.SELECTED DRAWING: Figure 2 【課題】配管接続筒部(21)と、レバー部(25)が突出する操作ハンドル(20)とを備え、ガス栓(2)が開状態にあるとき、レバー部(2)は配管接続筒部(21)に沿って位置するガス栓に装着させる誤操作防止具において、開状態にあるガス栓がいたずらや誤操作により閉栓される不都合を防止すると共に、構成部品を少なくし、小型で且つ配管周りの障害や邪魔にならないように装着できるようにすること。【解決手段】レバー部(25)に係止可能な係止部(10)と、配管接続筒部(21)の外周面の少なくとも一部に外嵌状態に係止可能な脚部(11)とが、一つの防止具本体(1)に設けられ、ガス流路の開状態でのみ、係止部(10)はレバー部(25)に、脚部(11)は配管接続筒部(21)に、それぞれ同時に係止可能に設定されている。【選択図】図２
