A quick-coupler for coupling a tool such as an excavator bucket, a clamshell grapple or demolition shears to a tool guide such as an excavator arm or the like, includes a coupling mount for receiving a first locking part and a locking mount for receiving a second locking part, wherein a securing element, which can be actuated by a pressure medium, is associated with the coupling mount for capturing and/or securing the first locking part and a locking element, which can be actuated by a pressure medium, is associated with the locking mount for locking the second locking part in the locking mount. The securing element of the coupling mount can likewise be actuated by the pressure circuit for actuating the locking element of the locking mount, wherein a time control device is provided for reducing the actuation pressure built up at the securing element within a specific time duration. |
