    • A receiving part is provided for receiving a rod for coupling the rod to a bone anchoring element, the receiving part including a receiving part body (5) with a top end (9a) and a bottom end (17b); a rod receiving portion (9) with a channel (12) for receiving the rod (6), and a head receiving portion (17) for accommodating a head (3) of the bone anchoring element, the head receiving portion having an open end (19, 17b) and being flexible so as to allow introduction and clamping of the head; and a locking ring (8) embracing the head receiving portion (17), wherein the locking ring can assume a first position in which it is latched with respect to the receiving part body (5) and in which the head can be introduced into the head receiving portion (17) and a second position in which it is latched with respect to the receiving part body (5) and compresses the head receiving portion such that the head is clamped but is not locked. A method for assembling a bone anchoring device is provided, the method including providing the receiving part body with the locking ring in a first position in which it is latched with respect to the receiving part body and in which the head can be introduced into the receiving part body and can freely pivot therein; inserting the head; and moving the locking ring (8) and the receiving part body (5) relative to each other until the locking ring enters a second position in which it is latched with respect to the receiving part body and in which the bone anchoring element is held in an adjustable angular position but is not fully locked.
    • 的接收部被设置用于接收杆的杆联接到骨锚固元件,所述接收部分包括:接收部主体(5)具有顶端(9a)和一个底部(17b)的端部; 具有用于接收所述杆(6)用于容纳头部(3)的骨锚固元件的,具有开口端的头部接收部的通道(12),和一个头部接收部分(17)的杆接收部分(9) (19,17B),并是柔性的,以允许头部的引入和夹紧; 和锁定环(8)拥抱头部接收部分(17),worin锁定环可以假定其被锁存相对于所述接收部主体的第一位置(5),并且其中所述头部能够被引入到所述 头接收部分(17)和在其被相对于所述接收部主体(5)锁存并压缩检查的头部接收部所做的头部被夹住,但没有被锁定的第二位置。 提供了一种用于组装骨锚固装置的方法,该方法包括:提供接收部主体处于第一位置时,锁定环在它被锁存相对于所述接收部主体,并且其中所述头部能够被引入到所述接收 部本体和可自由枢转。其中; 插入头部; 和移动所述锁定环(8)和所述接收部主体(5)相对于彼此,直到锁定环进入其中它被锁存相对于所述接收部主体,并且其中所述骨锚固元件被保持在第二位置 可调整角度位置的,但没有被完全锁定。
