Cargo securing fitting

A cargo securing fitting comprising a base coupling member having a circular socket portion therein and, said circular socket portion including a plurality of outer spaced base coupling lugs projecting radially inwardly of the inner periphery of said socket portion and a circular central pillar extending upwardly of said socket portion to the same level as said base coupling lugs to define a substantially annular channel between said central pillar and the inner periphery of said socket portion, said central pillar being provided with a plurality of inner spaced base coupling lugs projecting radially outwardly of said central pillar in diametrically opposed relationship to said outer base coupling lugs;

• and a removable cap coupling member having a circular plug element projecting downwardly thereof, said plug element including a plurality of outer spaced cap coupling lugs projecting radially outwardly of the outer periphery of said plug element and a circular central recess formed in said plug element on its lower surface to define an annular projection for receiving in said annular channel, said central recess being provided with a plurality of inner spaced cap coupling lugs projecting radially inwardly of the periphery of said central recess in diametrically opposed relationship to said outer cap coupling lugs, said outer and inner coupling lugs on said cap coupling member being arranged to engage said outer and inner cap coupling lugs on said base cap coupling member, respectively, by turning said cap coupling member relative to said base coupling member either clockwise or counterclockwise when said annular projection on said plug element is in said annular channel in said base coupling member.
