Abstract: A safety deck clamp for removably attaching and supporting the pole of deck torch or other item to a vertical deck rail. The safety clamp may be molded as a unitary part and formed with a three-sided yoke at one end substantially in a U-shape with a pair of resilient arms, the yoke being joined to an annular collar by a neck. The arms extend to a pair of detent prongs shaped as inwardly-facing right triangles that slightly overhang the arms. The resiliency of the arms works with the overhanging triangles to releasably lock the deck clamp onto the vertical deck rail. A circular collar supported by the neck has a closed or open circular recess for insertion of the torch pole. In addition, a shoulder is offset beneath the arms of the yoke for biting and supporting the clamp against the vertical deck rail.
