A connector for connecting implements on tools such as digging devices to a boom or the like comprises a body (1, 3) having first connection elements (8, 9) enabling the body to be mounted on a carrying device, second connection elements for engaging an implement with the (1,3) in the form of spaced apart first and second recesses (12, 11) on the body. The respective connection elements are mutually oriented for mounting the connector on the carrying device with the first recess (12) opening substantially downwardly and the second recess (11) opening in a direction substantially at right angles to the direction of opening of the first recess (12). At least the first recess (12) having an entrance and being substantially closeable by a closure member (13). A fluid pressure operated piston (34, 21) and cylinder (30, 22) assembly moves the closure member (13) toward or away from a position wherein the closure member substantially covers the entrance to the first recess. A spring device (31, 16) moves the closure member (13 ) toward or away from a position wherein the first recess (12) is substantially open. |
