A quick coupler (1) for attaching a tool (2), comprising an attachment bracket with two parallel attachment pins (3a, 3b), to an earth moving vehicle, where the quick coupler (1) comprises a frame (4) with a first cutout (5) and a second cutout (6) arranged substantially perpendicular to each other, which are adapted to cooperate with the respective attachment pin (3a, 3b) of the tool (2). The quick coupler (1) further comprises at least one, in relation to the frame (4) moveable locking arrangement (9), adapted to delimit the second cutout (6) in a direction parallel to the first cutout (5), whereby one of the attachment pins (3aq, 3b) of the tool is locked in the second cut-out (6) and at least one locking segment (18a, 18b) arranged to be rotated in relation to the frame (4) in at least a first and a second direction between different positions, whereby the locking segment (18a, 18b) in at least one position delimit the first cut-out (5) and locks the second of the attachment pins (3a, 3b) of the tool.
