An accessory mounting fixture for a vehicle is provided. The accessory mounting fixture includes a fixture body connectable to a vehicle surface and having a substantially U-shape defining a frontal opening and adapted to receive an accessory portion. The accessory mounting fixture also includes a locking assembly adapted to selectively secure the accessory portion within the frontal opening. The locking assembly has a first lock member pivotally connected to the fixture body on a first side of the frontal opening and a second lock member pivotally connected to the fixture body on the second side of the frontal opening. The first and second locking members are operable between a closed position for confining the accessory portion within the frontal opening, and an open configuration. Positioning the first and second lock members in the closed position secures the accessory portion within the frontal opening.
