A quick change attachment for joining a working implement to a bearing part has a first quick change part linked to the bearing part and having a first fastening device with a first fastening part and a second fastening part, and a second quick change part linked to the working implement and having a second fastening device with third and fourth fastening parts. The first fastening part may engage the third fastening part and the second fastening part may engage the fourth fastening part to join the first quick change part to the second quick change part. The first quick change part (17) has a first section (30) spaced apart from a second section (31) of the second quick change part (18) by a predetermined first interval (e) when the quick change parts are assembled. The quick change attachment has an elastic part (19) on the first or second sections (30, 31) that in the unstressed state has a predetermined thickness (d) larger than the first predetermined interval (e), so that when the quick change parts are assembled the elastic part exercises a compression force between the first and second sections. |
