A device consisting of a short chain fitting is linked to the floor of a transportation vehicle, such as a flatbed trailer. The chain fitting has a cap on one end thereof, which is installed in a mating aperture formed in the vehicle floor. The cap is installed on the top side of the floor with a short chain piece attached thereto running through the aperture with a second cap at the lower end which is secured to the lower end of the chain. A length of securing chain is attached to the chain fitting, this length of chain running substantially vertical to the floor and attached to cargo to be restrained. The cap is partially beveled along its contact surface with the floor and engages the sides of the aperture on the top part of the floor. The cap itself and the beveled surface thereon facilitate detachment of the chain fitting when so required.
