An infusion set for administration of fluid to a subcutaneous layer includes a cannula housing adapted for mounting onto a patient's skin and a needle housing for connection to the cannula housing. The needle housing has a pair of flexible sidewalls and a resilient band connected to the sidewalls. The resilient band is lockably engageable with the cannula housing to thereby secure the housings together, and is releasable from the cannula housing when the sidewalls are pressed toward each other to deform the resilient band. A hollow needle extends out of a main body of the needle housing for delivering fluid to the cannula from a fluid source. The walls of the needle housing extend beyond a distal end of the hollow needle to prevent needle contact with contaminated surfaces and inadvertent injury.
