Abstract: A large umbrella includes a plurality of ribs and stretchers and a connecting piece mounted to a mediate section of each rib for connecting the rib and associated stretcher. The connecting piece is substantially U-shaped and has a base section with two ends and a lateral wall extending from each end of the base section. A protrusion projects from an inner side of each lateral wall to form a pair of aligned protrusions adjacent to the base section for securely engaging with the rib. A pair of aligned holes are formed in the lateral walls adjacent to the distal ends of the lateral walls for allowing riveting of the stretcher.
