This invention relates to the field of electrical connection devices, and particularly to a quick-connection device. A quick-connection device includes a plug and a socket, which are inserted into each other. One of the plug and socket has a protrusion, and the other has a groove. The protrusion can engage with the groove as the plug moves. One of the plug and socket also has a positioning element, and the other has a positioning groove. The positioning element can elastically abut against the plug or socket. During the insertion process, the positioning element is elastically abutted. After the plug rotates a preset angle around its axis, the positioning element elastically resets and engages with the positioning groove, while the protrusion engages with the groove as the plug rotates. Its advantages are that it avoids accidental insertion or misplacement of the plug into the socket, and also prevents the plug from coming out of the socket.
