A device is provided for attaching a first part in the form of an instrument or tool to a second part in the form of a beam or such on a working machine having, on each of the parts, one engagement member fixed thereto, which are designed to be driven into engagement with each other so that the force of gravity on the first part holds the parts attached to one another. A first (17) of the engagement members is of the male-type having external surfaces converging towards each other and a second of the engagement members is of the female-type having internal surfaces converging towards each other in a corresponding way to said surfaces of the first engagement means for receiving and holding the first engagement means in the second engagement means under the influence of the force of gravity on the first part. |
