Abstract

The invention relates to a device for connecting a longitudinal support (1) to a bone anchorage element inside a spinal fixation system. This device consists of the following: a connecting segment (10, 30) having a central axis (4) and a through-opening (11) perpendicular to the central axis (4) for accommodating a longitudinal support (1); a tensioning-screw (23) which can be screwed in from the top end (28) of the connecting segment (10, 30); and a cylindrical hollow spring chuck (7) which is fitted coaxially in the connecting segment (10, 30) and has an open through-cavity (15) in the direction of the central axis (4) for elastically accommodating the head (5) of a bone anchorage element (30). The spring chuck (7) rests axially in the bore hole (6), in the direction of the bottom end (29) and near the bottom end (29) of the connecting segment (10, 30), without this impeding the radial mobility of the spring chuck (7). The device also comprises an insert (9) which can slide coaxially in the bore hole (6) of the connecting segment (10, 30). Said insert (9) has a bore hole (14) which is complementary to the outer surface (32) of the spring chuck (7).
