Claim 10:
11. In combination, a structure with a weld-on hook assembly, comprising:
a hook body having a shank portion and a free end portion disposed in a common plane with a closed end of the hook body defined between said shank portion and said free end portion, and a hook opening defined by said shank portion and said free end portion having an open side facing away from said closed end, said hook opening being arranged for receiving an item to be engaged by said hook assembly, said shank portion having a weldable base on a side opposite from said hook opening, said base being welded to the structure to allow the hook assembly to be used as a weld-on attachment point on the structure;
said free end portion of the hook body having a tip end portion with a through passage comprising a key slot; and
a removable pin assembly having a pin member received in said through passage to substantially close an open side of said hook opening to retain items within said hook opening, said pin member comprising a protrusion that mates with said key slot when the pin member is rotated to a first position to allow said pin member to be received in and removed from said through passage, and said protrusion serving as a locking structure that prevents said pin member from being removed from said through passage when said pin member is rotated away from said first position.
