Abstract: A tool wrist strap having a band, a looped cord and a clench bead on the cord. The band is made of a flexible elastic fabric material and formed by an elongated strip having opposite ends attached together. The band is preferably adapted to fit loosely about a person's wrist. The looped cord is composed of flexible inelastic material and has a looped end portion and a pair of opposite ends attached to the band adjacent to one another. The clench bead is slidable on the looped cord and produces sufficient friction therewith to hold the bead in any given position along the cord. The bead can be slidably moved by a person's hand in opposing directions away from and toward the looped end portion of the cord for respectively untightening and tightening the looped end portion in a noose-like configuration about a portion of a tool.
