Abstract: A connection device for a playyard consists of a handle and two connectors. The handle is provided integrally with a block and a plurality of protrusions having a hole therein. A pair of connectors is each provided with a plurality of spaces for receiving supports and a projecting portion having a pin stably secured therein or pivotally connected with the protrusion. When the handle is connected with the connectors by a fastener, and a holding portion is in horizontal position, the connectors are not able to be folded because of the restriction of the block within two stops of the connectors, and when the holding portion is in vertical position, two connectors are able to be folded together.
