A protective cap for use with a luer lock system. The protective cap includes a tubular body having an inner surface and a closed end. Internal threads are formed on the inner surface which are sized and shaped to engage with an external threads on the associated luer component. A crush thread is formed adjacent to a portion of the inner threads and protrudes radially inward from the inner surface of the protective cap. The crush thread is configured for engagement with the external threads on the luer component such that when the protective cap is threaded onto the luer component, the crush threads frictionally interfere with the external threads. This frictional interference resists decoupling and thus removal of the protective cap from the luer component.

[ What is claimed is:] [1.] An intravenous system for the introduction of an intravenous fluid into a vein of a patient, comprising:a source of the intravenous fluid;a flow-through conduit extending between the source of the intravenous fluid and the vein of the patient, the conduit providing communication between the source and the patient to facilitate introduction of the intravenous fluid from the source into the vein of the patient;a medical luer component disposed along the conduit between the source and the patient, the component having an elongate tubular body and an end with external threads;a protective cap sized and configured to fit over the end of the medical luer component;a tubular body included in the protective cap, the body having an inner surface and a closed end;internal threads included in the protective cap and being disposed on the inner surface of the body, said internal threads being sized and shaped to engage the external thread on said medical luer component for coupling said protective cap with said medical luer component to form a medical luer connection;a crush thread included in the protective cap and being formed adjacent said internal threads, the crush thread protruding radially inwardly for contacting and interfering with said external threads on said medical luer component; andthe crushed thread having properties for being crushed upon itself by the external thread of the medical luer component to increase the torsional resistance decoupling of the protective cap from the medical luer component.
