Connection element for connecting a bolt-supported part with the supporting bolt

A connection element for connecting a part-to-be-supported by a bolt (2) having an outer thread (3) with the bolt (2), the connection element comprising a member (1) for receiving the bolt (2) and fixedly securable to the part, the member (1) having a bore (5) through which the bolt (2) is to-be-extended, the bore (5) having a cylindrical receiving region (4), and a tapering, in a direction opposite to an insertion direction (A) of the bolt (2), region (7) that adjoins the cylindrical receiving region (4) at a side thereof facing in the direction opposite the insertion direction (A), the receiving member (1) further including a guide region (11) that adjoins the cylindrical receiving region (4) at an insertion direction side thereof and has an inner diameter (d3) which at most corresponds to an outer diameter of the bolt;

• and at least one locking member (8) arranged in the bore (5) and formlockingly engaging, at least partially, in the outer thread (3) of the bolt (2) for retaining the bolt (2) in the bore (5), the locking member (8) being formed as a radially expandable ring body an inner width (w) of which is at least partially smaller than the outer diameter (d2) of the bolt (2) and an axial length of which somewhat corresponds to a length (1) of the cylindrical receiving region (4).
