Abstract: A universal end connector for releasably coupling together aligned ends of a floating boom or the like is disclosed. The end connector is formed with a normally vertically extending body having a first side adapted for mounting to the end of the boom and a second coupling side formed as a yoke-like bifurcated side having a pair of spaced apart neck portions terminating in enlarged head portions. The neck and head portions define a throat and enlarged cavity therebetween dimensioned for receipt of the head and neck of a similarly formed second end connector. The throat and cavity of the end connectors are open at at least one of a top and a bottom end thereof to permit selective positioning of the end connectors in coupled and uncoupled relation. The enlarged head of the end connector is preferably formed with inwardly facing and inclined surfaces on either side of the head so as to cause the head portions to be pulled together and narrow the throat to enhance coupling under normal loading of the connector.
