A medical article, such as a connector fitting, is stabilized on a patient with a retainer having a base and moveable walls. Actuation surfaces configured to move the walls in at least a lateral direction towards each other are suspended above the base by a pair of supports. When pressed together, inner surfaces of the walls form a channel configured to encircle the medical article. The medical article may be pressed down against the actuation surfaces by a medical provider to cause the walls to encircle the medical article. Thereafter, the medical provider may snap the walls together using a latching mechanism to stabilize the medical article on the patient.
