ABSTRACT:
A connecting assembly comprising a pair of substantially identical connecting members having a base ring connected to an upper tubular inflatable portion of an oil containment boom, and a depending arm adapted to engage a depending skirt of an oil containment boom. Each base ring comprises first and second interlocking members in the form of grooves and flanges adapted to interfit with one another in order to attach two segments of oil containment booms together. When offset angularly and placed face to face, with the groove of the final connecting member aligned with the flange of the second connecting member, and the flange of the first connecting member aligned with the groove of the second connecting member, two connecting members may be rotated toward one another and locked together. External fastening devices located on the arm depending from the base ring prevent counter-rotation which would disassemble the connecting members.
