The invention discloses a tightening type pipe opening plug which comprises a pipe plug body. The pipe plug body comprises a cover, an outer wrapping face and an inner wrapping face, wherein the outer wrapping face and the inner wrapping face wrap a pipe wall. A lifting handle is arranged on the cover, one end of the lifting handle is vertically hinged to the edge of the cover, and a rotary tightening device is arranged on the lifting handle. The outer wrapping face is provided with a steel wire channel which surrounds a pipe body and is used for allowing a steel wire to penetrate. Compared with the prior art, according to the tightening type pipe opening plug, the steel wire is used for fastening the pipe wall, the steel wire is then rotated, tightened and lifted through the lifting handle, and thus the sealing effect to a pipe opening by the whole pipe plug body can be better.
