Retaining means with an axial passage for receiving a format part

A retainer with an axial passage for receiving a format part comprising:

• several clamping tongues facing in the direction of the format part, the clamping tongues being elastically deformable, the clamping tongues angularly aligned against an outer lateral surface of the format part to hold the format part stationary in a first movement direction, the format part being movable in a second movement direction opposite to the first movement direction;
• at least one adjuster, contact between the respective clamping tongues and the format part being released upon movement of the adjuster in the second movement direction, the format part as a result being movable in the first movement direction for removal;
• and
• an upper base body and a lower base body, together forming a conical inner space, within which the angularly aligned clamping tongues or the format part are at least partially arranged when the outer lateral surface of the format part is in contact with the clamping tongues, the clamping tongues being part of a one-piece component of the retainer, the one piece component arranged between the upper base body and the lower base body, the upper base body being fixable via bore holes to the lower base body or the one-piece component being fixable via bore holes to the upper base body or to the lower base body, the one piece component being fixable via the bore holes by a screw connection.
