Abstract: A one piece molded vacuum tube holder is fitted with a one piece molded needle hub assembly. A needle protection device is further rotatably mounted to the neck of the one piece vacuum tube holder. One portion of a locking mechanism is provided at the neck of the one piece vacuum tube holder and a second portion of the locking mechanism is provided at the needle hub of the needle hub assembly, so that when the needle hub assembly is press fit to the vacuum tube holder, the two portions of the locking mechanism will coact to fixedly retain the needle hub assembly within the vacuum tube holder. The one piece vacuum tube holder is configured to have an elongate needle cover integrally extending from its neck. A finger grasp mechanism may be coupled to the needle cover.
