A forceps made in one piece of a plastic material has two arms having each a flat tip of a rectangular or square configuration. Said tips face each other and the arms are of a rigid beam-shaped structure but join in flexible portions. Near to the transition between said beam-shaped structure and said flexible portion each arm has a projection and said projections are dimensioned to engage each other when said tips are pressed against each other surface to surface.
