Coupling device for coupling a rod to a bone anchoring element and method of manufacturing the same

A coupling device for coupling a rod to a bone anchoring element, the coupling device comprising:

• a receiving part having a first end and a second end below the first end, a central axis extending through the first end and the second end, an accommodation space for accommodating a head of the bone anchoring element, an opening at the second end, and a recess at the first end for receiving the rod, the recess forming two legs;
• and
• a pressure member arranged at least partially in the accommodation space, the pressure member being adjustable from a first configuration where a topmost end of the pressure member is at a first axial position and an inserted head is pivotable in the accommodation space to a second configuration where the topmost end of the pressure member is at a second axial position below the first axial position and the pressure member exerts pressure onto the inserted head to provisionally lock the inserted head;
• wherein at the second configuration, a latching connection is formed between the pressure member and the receiving part to at least temporarily prevent the pressure member from being adjusted back towards the first configuration.
