A connector ( 1 ) for a spinal osteosynthesis device, for connecting two rods to a plate fixed in a vertebra, includes a first orifice ( 2 ) opening onto two opposed faces ( 3, 4 ) or the connector ( 1 ), and two other orifices ( 5, 6 ) opening onto two other opposed faces ( 7, 8 ) of the connector ( 1 ). Each of the two other orifices ( 5, 6 ) are each designed to receive a rod ( 14, 15 ) of the osteosynthesis device. The connector ( 1 ) includes means making it possible, when the connector ( 1 ) is push-fitted onto a protrusion ( 100 ) of a bone anchor member, to tighten the rods ( 14, 15 ) simultaneously in the two other orifices ( 5, 6 ) when a nut ( 22 ) is screwed onto the protrusion ( 100 ). An assembly for spinal osteosynthesis device incldues a plate ( 16 ) that includes a protrusion ( 100 ), a connector ( 1 ) as previously described, and a nut ( 22 ).
