Abstract

A rigid stabilizer sleeve 56 is slidably received over a drill collar 54. A pair of internal clamping rings 83, 74 are slidably received through each end of the rigid main sleeve. As a threaded end cap 12 is threaded into the rigid main sleeve, the end clamp forces one ring of the pair against the other thereby producing a clamping effect whereby the stabilizer can be clamped at any desired position on the drill collar 54. The ring 83 of the pair has a groove 84 and a rib 82 disposed on its interior cylindrical surface, which groove and rib interlock with a rib and a groove disposed upon the outer cylindrical surface of the end cap 12, whereby when the end cap is threadedly removed from the rigid main sleeve, the ring 83 follows the end cap and is disengaged from the inner ring 74, thereby unclamping the pair of rings from the drill collar. <IMAGE>
