摘要:
An element with a shank (1) and a holding element (2) connected to it for connecting to a rod (100) is provided, wherein the holding element (2) has a recess (3) having a U-shaped cross-section for receiving the rod (100) with two legs (4, 5) open at one end (6) and an inner thread (7) on the open legs (4, 5) and a locking element (9) with an outer thread (8) which cooperates with the inner thread of the legs, wherein the inner thread (7) of the legs and the outer thread (8) of the locking element are constructed with a flat thread in which the two flanks (7a, 7b; 8a, 8b)) enclose an angle of 90° in each case with the screw axis (S, M). This prevents splaying of the open legs when the locking element is screwed in. The flat thread is easy to produce.
