Patent ID: 7934896

Claim:
A nut, comprising: an internal thread; and at least two parts, each of the parts including a section of the internal thread which is radially pushable onto an external thread; and cooperating connecting elements which allow a relative displacement of the parts in a direction running radially to an axis of the internal thread until reaching a use position in which the internal thread of the nut surrounds the external thread with a small clearance, the connecting elements having guide surfaces which are inclined by an angle to a plane running radially to the axis of the internal thread and which guide the parts of the nut in displacement into the use position in a rotational movement about an axis of rotation running across the axis of the internal thread, wherein at least one part has at least one locking arm which has on only one side a guide surface, which induces a rotational movement when the parts are displaced and is in contact with a complementary guide surface of the other part.
