摘要：
A bone anchoring device is provided comprising
a bone anchoring element (1, 1') having a shaft (2) for anchoring in the bone and a head (3, 3');
a receiving part (5) for coupling a rod (6) to the bone anchoring element, wherein the receiving part comprises
a first portion (9) with a first end (9a) and a second end (9b) and a U-shaped recess (12) for receiving the rod, the recess (12) extending from the first end (9a) in the direction of the second end (9b) thereby forming two free legs (12a, 12b) and
a second portion (16) at the side of the second end (9b) opposite to the first end for accommodating the head (3, 3'), the second portion having a free end (17) and being flexible so as to allow introduction and clamping of the head;
a locking ring (8) embracing the second portion (16);
wherein the head (3, 3') is locked by means of exerting pressure with the rod onto the locking ring (8) resulting in compression of the second portion of the receiving part and
wherein the locking ring (8) is mounted to the receiving part from the free end (17) of the second portion (16).
