A pair of lifting eye assemblies are connected during the lifting operation at each respective end portion of the bar, each forming a connection with an above supporting bridle line and a depending lift line, each of the lifting eye assemblies comprising in part a socket of uniform cross-section receptive of one end of said bar thereinto and having a corresponding internal cross-section equal to or slightly larger than the external cross-section of the support bar. A stop is provided within the socket for limiting the penetration of the bar into the socket.
