A device for use in detaching a segment filled with blood from a blood transfusion bag and at the same time making a tear in the segment so that the blood contained therein can be extracted for test purposes is disclosed. The device comprises a unitary rigid structure molded from plastic and having a pair of channel shaped cavity sections hingedly interconnected and sized and shaped so as to fit around at least a portion of the sample segment to be removed along its length, with one cavity section on each side thereof. A pair of projections, each terminating in a sharp point, are formed on one of the cavity sections. One of the projections is positioned so that it penetrates and produces a tear in the end seal at the inner end of the sample segment when the sample segment is placed properly in the device and two cavity sections are closed around the sample segment, the tear enabling the sample segment to be easily pulled or broken off from the blood transfusion bag. The other projection is positioned so as to penetrate and produce a break in the sample segment itself so that the blood contained therein can be easily extracted.
