1. In combination:

  • (A) a shaft having a groove about its outer circumferential surface;

    (B) a sleeve having a central bore for receiving said shaft therethrough, said central bore having an eccentric circumferential groove about its inner surface;

    (C) at least one detent, said detent being an arcuate spring having an associated radius smaller than the radius of said groove in said shaft, an associated height greater than the depth of said groove in said shaft, said detent being depressible during assembly and disassembly; and

    (D) means for circumferentially positioning said detent in said groove in said shaft including at least one spacer which has a geometry which prevents said spacer from rotating circumferentially about said shaft and from interfering with the rotation of said sleeve relative to said shaft;

    whereby after assembly said detent straddles the interface between said shaft and said sleeve, being within both of said grooves simultaneously, thereby preventing axial movement of said sleeve relative to said shaft.
