ABSTRACT:
A locking device for threaded fasteners includes a unitary flexibly shape-retaining body having portions nonrotatably engaging the heads of each of a pair of bolts, and a medial interconnecting bar portion which mutually prevents rotation of the portions and of the engaged bolts, while also deformably allowing for variable spacing between the pair of bolts to be accommodated. A resilient retainer pin removably secures the locking device to each bolt head. The locking device may be reused many times without detriment to its locking function.
