The utility model relates to a wing needle safety sleeve, which is used to cover a wing needle. The wing needle safety sleeve has a needle part, a tube part and two wings. The wing needle safety sleeve comprises a connecting ring, two arc-shaped slices, two guide channels and two reverse stops.The opposite sides of the ring surface of the connecting ring are respectively provided with a holding opening.Each guide channel has a guide groove and an oblique groove.The two backstops are formed by the connecting rings extending toward the two holding openings respectively, and the two backstops are close to the two oblique grooves respectively.When the two wing parts of the wing needle are located at the two holding openings, the two backstops can prevent the two wing parts from detaching through the two holding openings and restrict the two wing parts to the two holding openings.一種翼狀針安全套管，用以套合一翼狀針，該翼狀針具有一針部、一管部及二翼部，該翼狀針安全套管包含一連接環、二弧形片體、二導引通道及二逆擋部。該連接環之環面相對側分別穿設有一容置口。各該導引通道具有一導引槽及一斜向槽。該二逆擋部係由該連接環分別朝向該二容置口延伸所形成，且該二逆擋部分別靠近該二斜向槽。其中，當該翼狀針之二翼部分別位於該二容置口時，該二逆擋部能防止該二翼部分別經由該二容置口脫離，而將該二翼部分別限制於該二容置口。
