Abstract: A workbench includes a top with four legs connected to an underside thereof by four connection devices. Each connection device includes a connection member with a first tapered tube and a stationary member with a second tapered tube. Each of the first and second tubes has a flange extending inward therefrom. Four sleeves are respectively engaged with the aligned first and second tubes and each sleeve has two first grooves with which the flanges of the first and second tubes are engaged. Four legs are securely inserted into the four sleeves. Each sleeve has a lip in an inner periphery thereof and each leg has a second groove with which the lip is engaged. The relative positions between the first tube, the second tube, the sleeve and the leg are maintained by the flanges, the lip and the grooves.
