ABSTRACT:
A unitary lockable turnbuckle constructed from an elongated member, which is partially slit at two axially spaced-apart locations so as to form an interconnected barrel with a nut at each end. A thread is formed in each nut and the adjacent portion of the barrel, the thread at one end being of opposite hand from the thread at the other end. The slits leave reduced shear sections which break when the nuts are sufficiently torqued in opposition to the barrel. Preferably the width of the slit is reduced substantially to zero before the thread is formed.
