A torque device capable of both securement to a guidewire and release with only one hand, is constructed of a pair of tubular elements, one terminating in a series of prongs with outer surfaces which form an outwardly expanding cone, and the other surrounding the prongs and containing an internal, inwardly extending flange which engages the outer surfaces of the prongs. When the tubular elements are slid apart relative to each other, the flange travels along the expanding outer surfaces of the prongs, forcing the prongs toward each other so that the prong tips grip the guidewire. Release is achieved by sliding the tubular elements back to a closed configuration.
