Open-End Ratchet-Like Wrench With Releasable Locking Head Abstract of the Disclosure A two way open-end wrench has a rotatable, captive, split socket which is selectively locked and unlocked to the wrench handle for torque transmittal through the meshing engagement of two opposed sets of teeth. One set is disposed around the periphery of the open-sided socket member and the other within the forward, concave end of a spring-loaded coupler disposed partly within and partly outside the wrench body. Engagement of the teeth is effected by the inward movement of the coupler when a user grips the wrench handle preparatory to turning it. Relaxation of the grip at the end of a stroke permits the handle to be returned to the starting position while the socket remains stationary. A projecting extension on the socket provides for manual rotation to the open position, permitting the tool to be withdrawn from a fastener on a tubing line, pipe or cable.
