The invention comprises of improvements in a locking puller device. The locking puller device has three pivotally mounted jaws and a cam ring which moves forward to pivot and lock the jaws about an object. The improvements comprise a flange-less, disk-like collar having axial slots therein to pivotally mount the jaws, a threaded sleeve which is threaded into a receiving member of the collar, and a T-handle which replaces the nut and which can be adjusted without a tool. These improvements vastly improve the strength and durability of the locking puller device and also are more user friendly. If the threads on the sleeve are damaged through use, the sleeve can be turned out of the collar and replaced with a new sleeve of various lengths, instead of having to also replace the collar which was fixed to the sleeve in the old locking puller devices.
