In a concrete-feeding bucket, the base of which has a segment hinged closure with blocking members working in opposite directions, the segment plates of which each free half of the bucket outlet or close it with front edges lying one on top of the other, it is provided according to the invention that a support, fixed to opposite walls of the bucket, bridges the outlet above the segment plates and the closed position of their front edges in the bucket outlet, parallel to the closing edges of the segment plates, and reinforces a moulding which has a bead which is elastically deformable by means of the segment plates when the blocking members are moved in opposite directions and which provides a seal on the inner edges, adjoining the front edges, of the segment plates.
