ABSTRACT:
The invention provides an anchorage device for a cable with multiple strands (2) comprising a block (1) in which the strands are anchored individually by radially clamping about each strand a split truncated cone shaped jaw (3) surrounding this strand and housed in a complementary housing (4) of the block. This device comprises a single thrust member (6) disposed axially opposite the different jaws (3) and a plurality of spacers (10) each interposed axially between said member (6) and a jaw (3) about the strand end (2) clamped by this jaw, said spacers (10) being identical to each other, formed from a metal or an alloy whose deformation/stress characteristic has a long plastic flow plateau and dimensioned so that at the end of the thrust the deformation of each of them has reached, but not exceeded, the plastic flow stage thereof.
