A bone anchoring device includes a receiving part having a central axis, two legs defining a recess for receiving a rod, and a head receiving portion that is at least partially expandable and having an opening for inserting and pivotably holding a head of a bone anchoring element therein, and a locking ring mountable around the head receiving portion in an axial direction while a rotational orientation of the locking ring relative to the receiving part remains constant. When the locking ring is around the head receiving portion, the locking ring is rotatable around the central axis from a first rotational orientation to a second rotational orientation where a compressive force exerted by the locking ring on the head receiving portion is greater than at the first rotational orientation.

A polyaxial bone anchoring device includes a receiving part with an upper member having a first end, a second end, and a recess at the first end for receiving a rod, and a lower member connectable around the second end of the upper member, and a pressure member positionable in the upper member to exert pressure on a head of a bone anchoring element. The lower member is movable from a first position where the head is pivotable, to a second position closer to the first end of the upper member where an angular position of the head is locked while the recess remains vacant or unobstructed. When the lower member is at the second position, at least part of the lower member is aligned axially with at least part of an end face at the second end of the upper member.
