- a sleeve having a helical groove;
the helical groove having spaced depressions and opposing side walls;
a one-piece end cap having an interior wall;
the interior wall having a lug;
the end cap positioned over the sleeve such that the lug fits within the helical groove of the sleeve whereby the end cap is secured to the sleeve;
whereby said lug is the only structure securing said end cap to said sleeve, and whereby said lug is sized to fit snuggly within said helical groove such that said helical groove opposing side walls prevent extension or retraction of said end cap relative to said sleeve except when said end cap is rotated relative to said sleeve.

20. An adjustable tip for a lancet comprising:
-
a sleeve having an exterior sidewall; a helical groove formed in said exterior sidewall, said helical groove having opposing side walls, an inside wall and spaced depressions; a one-piece end cap having an interior wall; a single lug extending from said interior wall of said end cap; said end cap mounted onto said sleeve such that said lug fits within said helical groove of said sleeve whereby said end cap is secured to said sleeve, whereby upon rotation of said end cap relative to said sleeve said lug moves along said helical groove, thereby extending or retracting said end cap relative to said sleeve, and whereby said spaced depressions retain said lug against accidental movement; whereby said lug is the only structure securing said end cap to said sleeve, and whereby said lug is sized to fit snuggly within said helical groove such that said helical groove opposing side walls prevent extension or retraction of said end cap relative to said sleeve except when said end cap is rotated relative to said sleeve. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
