The morphine syrette used in World War II had a wire loop pin with a guard in the end of the hollow needle that was used to break a seal where the needle was attached to the tube. It was similar to a Superglue tube. After breaking the seal the wire loop pin was removed and the hollow needle was inserted under the skin at a shallow angle and the tube flattened between the thumb and fingers.
