The invention discloses a bracket-typed bandage which comprises a bandage body; the two ends of the bandage body are respectively provided with a card tongue and a card slot which has a top plate anda bottom plate; the space between the top plate and the bottom plate forms an opening facing the card tongue which can be inserted into the opening of the card slot so as to lead the bandage body to form a sealing ring; the end of the top plate facing the card tongue is provided with a wrench holding part for hand holding; by wrenching the wrench holding part along the direction which is perpendicular to the top plate and far from the bottom plate, the top plate and the wrench holding part move as a whole so as to lead the opening to stretch facing the card tongue, and both the wrench holdingpart and the top plate do not have the problem of elastic fatigue; in addition, the outer profile line of the arbitrary cross section of the bandage body, which is perpendicular to the enclosed ring center axis, is continuous, while the outer periphery and the inner periphery of the arbitrary cross section, which are parallel to the enclosed ring center axis, only consist of a straight line and/ora convex part; when in injection molding, the mold is not needed to release along the direction which is perpendicular to the enclosed ring center axis, but only needed to release along the directionof the enclosed ring center axis, thereby simplifying the mold design, reducing the production cost and boosting the production efficiency.
