ABSTRACT:
The tamper-proof samples clamp of the invention includes a holder section that is foldable into a pair of substantially parallel spaced clamp elements having apertures which, when the clamp elements are in their parallel relationship, are in alignment. At least one pin element projects from one of the clamp elements and possesses sufficient stiffness such that it can penetrate the material of samples positioned between the clamp elements. Self-locking fasteners are provided that are dimensioned and configured for insertion through each set of aligned apertures for drawing and locking the clamp elements in clamping engagement with the samples therebetween. A hanger structure is connectable with the holder section for rotatably supporting same and the samples clamped between the clamp elements.
