The invention relates to safety closing devices for containers of biological liquids and, particularly, for test tubes used for the drawing, transport and/or analysis of blood, of the type including an undercap and a cap, both made of a perforable materi- al. The undercap (2) and the cap (3) each include at least a central portion (4, 6), formed by one or more parts. The central portion (4) of the undercap is sealingly locked by the front side on the edge (9) of the test tube (1) and the central portion (6) of the cap is sealingly locked on the side facing the undercap, by an axial pressure applied by locking means (13, 15; 14, 16), that can be only intentionally disengaged by an operator, and allow reciprocal mechanical coupling of the cap to the undercap and the assembly thereof on to the prearranged end (15) of the test tube.
