Abstract: A clasp for the cords of a bola tie comprising two mating shell halves and a manually operable spring biased clamp disposed between the shell halves to provide an enclosed clasp which is releasable and which provides improved external appearance and mechanical function. The inner surfaces of the clasp which engage the tie ends are smooth non-abrading convex portions of toroidal-like surfaces and clasp the tie ends around an extensive part of the periphery of the cord and along extended portions of the cord. Although firmly clasping the cord ends the clasp may be forced along the cord ends without manually releasing the clamp.
