A device for attaching an identity tag and removing a tissue sample comprising: an ear-tag applicator ; a male part of the identity tag (male tag ) and a female part of the identity tag (female tag ) placed on said applicator a means to hold a sample container below a male tag and above female tag and below an ear to which the identity tag is to be attached and from which tissue sample is to be removed; wherein the means to hold the sample container below the male tag and above the female tag is a flap , that further connects the sample container to the male tag the male tag having a removable tissue cutting element ; the flap having at least one holder reversibly connected to the removable tissue cutting element and a clamp reversibly connected to the sample container ; the male tag having, by means of the ear-tag applicator a downward movement path toward the female tag ; and at least one part of the sample container or one part of the removable tissue cutting element having a feature that supports movement of the sample container out of the movement path of the male tag upon releasing of the clamp , wherein the sample container and the clamp remain in the movement path of the male tag when there is a connection between the clamp and the sample container , wherein the connection between the holder and the removable tissue cutting element and the connection between the clamp and the sample container are released after a tissue sample is removed which releasing is caused by the descending movement of the ear-tag applicator but before the male tag enters the female tag part , wherein when the connections are released the sample container retains the removable tissue cutting element or at least a part thereof and the sample container moves out of the movement path of the male tag . an ear-tag applicator ; a male part of the identity tag (male tag ) and a female part of the identity tag (female tag ) placed on said applicator a means to hold a sample container below a male tag and above female tag and below an ear to which the identity tag is to be attached and from which tissue sample is to be removed; wherein the means to hold the sample container below the male tag and above the female tag is a flap , that further connects the sample container to the male tag the male tag having a removable tissue cutting element ; the flap having at least one holder reversibly connected to the removable tissue cutting element and a clamp reversibly connected to the sample container ; the male tag having, by means of the ear-tag applicator a downward movement path toward the female tag ; and at least one part of the sample container or one part of the removable tissue cutting element having a feature that supports movement of the sample container out of the movement path of the male tag upon releasing of the clamp , wherein the sample container and the clamp remain in the movement path of the male tag when there is a connection between the clamp and the sample container , wherein the connection between the holder and the removable tissue cutting element and the connection between the clamp and the sample container are released after a tissue sample is removed which releasing is caused by the descending movement of the ear-tag applicator but before the male tag enters the female tag part , wherein when the connections are released the sample container retains the removable tissue cutting element or at least a part thereof and the sample container moves out of the movement path of the male tag . <EOS>
