Abstract: A deck-retaining clamp assembly secures a corrugated deck panel to a support cable that underlies and supports the deck panel, the deck panel having in a lower web portion an elongated opening that overlies a segment of the support cable and extends transversely of the support cable. A U-bolt engages the cable from below, and a clamp plate is tightened against the upper surface of the deck panel by at least one nut threaded onto one leg of the U-bolt. A handle attached to one of the legs of the U-bolt permits manipulation of the U-bolt to engage it with the support cable. The handle has a grip portion that is shaped and dimensioned such that it cannot pass through the hole in the clamp plate and a shank portion that is movable through the hole in the clamp plate and is of a length such that the U-bolt can be moved down relative to the clamp plate to a position such that the upper end of the U-bolt is at a level below the lowermost extremity of the support cable.
