Abstract
A connector for packings containing medical liquids, particularly infusion, transfusion or enteral bags, comprises a connecting part (1) for accommodating a spike for drawing out the liquid and comprises a closure part (3) that closes the passage (2) inside the connecting part (1). The connecting part (1) has an elastically deformable pinching off part (4) provided in the form of a tubular section with a non-circular cross-section. A base part (5), which widens on both sides is adjoined to said pinching off part (4) and can be integrated in the packing. During manufacturing, the packing is filled with liquid via the connecting part. After filling, the pinching off part is pressed together whereby preventing liquid from escaping. Afterwards, the closure part is placed onto the connecting part. The manufacturing of the packing is simplified by virtue of the fact that an additional tube for connecting the connector and packing is rendered unnecessary.
