Abstract: A strap latch device for securing a medical patient to the side rails of an examining or treatment table includes a pair of extending opposed claw arms, one fixed and the other spring biased to rotate towards the fixed claw arm with the arms overlying a rectangular recess in the latch between the arms. A lever is used to overcome the bias and separate the claw arms so that one edge of a side rail fits into the fixed claw arm and rotation of the latch on the rail projects to the moveable claw arm over the side rail with the side rail fitting closely into the defined recess. Upon release of the bias lever the side rail is grasped by the claw arms with projecting lips on the claw arms securing the rail into its recess. Patient motion and belt tension will tend to accentuate latch retention.
