A repair bracket that provides a substitute for one or more broken anchoring tabs of a manhole base. The repair bracket is an expansible bracket that has a frame member with a central manhole access passage through the frame member. The frame member has threaded holes transversely through the frame member and located at positions corresponding to positions of threaded holes in the original unbroken anchoring tabs of the manhole base. The threaded holes are used to connect the frame member to a manhole cover by threaded bolts extending through the cover and into the threaded holes. Expansible actuators are mounted to the frame member and are capable of moving a part of the expansible bracket outward into engagement against the inner wall of the base or a sleeve or casing attached to the base.
