ABSTRACT:
The assembly comprises two, snap-together pieces which, following their clinched or latched engagement, are freely rotatable relative to each other. One of the two pieces comprises a sleeve which has an inner annular land, and the other of the two pieces comprises a rod having flexible extending fingers which terminate in outwardly-directed, land-engaging and latching lugs. The rod is slid into the sleeve, with the lug-ended fingers entering first, and, consequently, the fingers are resiliently forced inwardly until the lugs reach the land. Then the fingers spring outwardly while the lugs latch onto the land. This latching together of the pieces requires no tools.
