Nut for threaded connection in an implant

Abstract

Abstract The invention shows a nut (1) for threaded connections in an implant, having a radially projecting contact shoulder (4) which presses axially against a housing part (5), an internal thread (9) fitting in a screw part (12) and shaped elements (14) on the side facing away from the housing part and intended for insertion of a tool for tightening the nut (1). According to the invention, leaf springs (2) projecting in the axial direction are formed on the nut and end as locking cams (3). When the nut (1) presses against the housing part (5) the locking cams (3) engage in a recess (6) on the housing part (5) when the contact shoulder (4) rests on it in order to prevent the nut from becoming detached from the housing part. <IMAGE>
