A running tool particularly useful for running liners on coiled tubing is disclosed. A torque-transmitting outer sleeve is employed which initially traps the collets. The collets are engaged to the liner by relative mechanical movement and thereafter lock in a secured position to the liner, regardless of whether the liner is placed in tension or compression by the running tool. Release is accomplished byletting down weight on the running tool, coupled with hydraulic pressure to shear a pin securing the collet mechanism. Upon such a hydraulic release with the pinsheared, the outer torque sleeve shifts downwardly to prevent relatching. Torqueis transmitted through the outer torque sleeved and not through the latching collets.
