A kind of tool noctilucence connecting piece, including at least in two outer ends of a connection ontology, pivot has two adapter units respectively, the outer surface of the connection ontology and two adapter unit is respectively provided with a noctilucence layer. Wherein the adapter unit can be change, buoy plug, fish hook, various fastener or other exchanging structures person. Wherein the connection ontology can be rotor structure as many as more than single rotor, birotor or birotor. Therefore the utility model directly can generate the fish-gathering effect that shines via connecting piece itself, effectively reduces element, assembling procedure and reduce the progressives benefits such as water resistance.一種具夜光連結件，其至少包含在一連結本體之兩外端分別樞結有二轉接單元，該連結本體及該二轉接單元之外表面分別具有一夜光層。其中該轉接單元可為轉環、浮標插座、魚鉤、各式扣件或其他轉接結構者。其中該連結本體可為單轉子、雙轉子或雙轉子以上之多轉子結構。是以，本新型可直接經由連結件本身產生發光集魚效果，有效減少元件、組裝工序及降低水阻等進步性效益。
