A spinal fixator (10) comprising vertebral fixation means, a mounting portion (11) extending along axis X-X' and including a housing (12) with an open side facing away from the fixation means and comprising opposite side openings for receiving a connecting rod (20) extending transversely to axis X-X' on either side of said mounting portion for attachment to at least one other spinal fixator (10'), a locking member (13) engageable with said mounting portion for locking said connecting rod within said housing, and an intermediate ring (30) rotationally symmetrical about axis X-X'. Said intermediate ring is a pre-tightening ring intended to be positioned on the mounting portion before the locking member is fitted, and capable of snapping onto the mounting portion and engaging the connecting rod to preposition same in the housing and make it easier to fit the locking member therein, regardless of the bend in said connecting rod.
