A system in which an umbrella's cover is connected to a rib tip by clamping (and not tying) the cover to the rib tip. The clamp connector is structured so that the clamping pressure between the umbrella's cover and rib tip is actually increased as the umbrella is opened in response to the cover being drawn taut over the ribs. The clamp connector, in preferred form, includes a ring receivable on a ring seat, the cover being clamped between the ring and ring seat, and the ring seat being receivable on the end of a rib tip.
