A fastening system 10 provides a fixed fastener 60 which may be removably interlocked with a strap fastener 20. The fixed fastener 60 is typically carried by a vertically oriented planar portion of a flatbed trailer, such as a section of the vehicle's frame. The fixed fastener 60 provides a base 61 and a hook 63, having ear and nose portions 67, 68. The strap fastener 20 is typically carried by the end of a strap 101 used to secure a load carried on the flatbed trailer. The strap fastener 20 defines a fastener opening 36 having left and right ear passages 38, 40, sized to allow passage of the fixed fastener 60 when the strap fastener is rotated so that the ear portion 68 of the fixed fastener 60 passes through one of the ear passages of the strap fastener. Such passage is almost impossible to result accidentally; therefore the fasteners will remain connected during use, and must be deliberately disconnected.
