Abstract: An electrical connector comprises first and second connector components, each component having a generally circular cross-section oriented perpendicular to a central axis that is common to both components. A rotatable coupling ring is retained on and substantially axially aligned with the first component. This coupling ring has a first end for engaging the second component and axially advancing the first component relative to the second component to urge the contacts of the first and second components into enngagement. The coupling ring also has a second end with a retainer groove that encircles the interior of the second end and that has a bearing surface in a plane substantially perpendicular to the common central axis of the first and second components. A retainer ring snugly engages the interior of the retainer groove. The retainer ring has a resiliently collapsible gap and also has an exterior retainer surface generally parallel to and engaging the bearing surface of the retainer groove.

Abstract: The one-piece aneurysm clip is fabricated from a predetermined length of round metallic rod or wire. The clip includes a pair of cooperable jaw portions and a coil portion that supplies a closing force to the jaws, doing so through first and second connecting portions. The first connecting portion has a longitudinal slot formed therein and the second connecting portion is U-shaped having a thickness correlated with the width of the slot so that the jaw portions are maintained in alignment. The degree of closing force supplied by the coil is determined by the width and depth of a slot formed in a segment thereof.
