An infusion set includes an infuser base, a cannula cartridge, a hub and a tube set connector. The infuser base includes an adhesive pad for removably adhering the infuser base to an infusion site, an infuser base opening and a barb. The cannula cartridge includes a cannula for subcutaneous insertion into the infusion site and a cannula cartridge self-sealing septum. The hub is configured for removable and user-controlled three hundred and sixty degree (360°) rotateable engagement with the barb. The hub includes a hub needle for piercing the self-sealing septum, thereby creating a fluid pathway from the hub needle to the cannula of the cannula cartridge, and a hub self-sealing septum. The cannula cartridge is configured for insertion into the infuser base opening with the cannula being subcutaneously inserted into the infusion site. The tube set connector includes a connector module configured for user-releasable attachment to the hub in a direction perpendicular to the direction of cannula insertion, a tube set connector needle for piercing the hub self-sealing septum, and a flexible tube in fluid communication with the tube set connector needle.
