ABSTRACT:
A pair of side-by-side oppositely facing and threaded eyebolts are provided and threaded in parallel side-by-side bores in a common nut structure to define a turnbuckle. One of the eye portions of the eyebolt is open defining an open throat hook with which a closed ring-type anchor member may be releasably engaged and a sleeve is mounted on the shank of the same eyebolt between the nut and the open eyebolt throat and is shiftable along the eyebolt shank into and out of position closing the throat for releasably locking an associated closed ring-type anchor member within the hook. The sleeve is engageable by the common nut structure for displacing the sleeve toward its throat closing position and the common nut structure additionally includes friction structure for adjustably frictionally resisting rotation of the shank portions of the eyebolts relative to the nut structure.
