A push-lock handle assembly includes segments that are interconnected by axial movement using snap-in D-shaped tabs and recesses. Slits and grooves allow the tabs to deflect slightly inwardly during insertion. In another form there is a grip section, at least one pole section, and one accessory attachment section. Simple axial movement snap locks the parts together.

1. A handle assembly, comprising:at least two elongated sections, one such elongated section having a male end, and another such elongated section having a female end; the female end defining an internal cavity and a recess spaced from a terminal edge of that elongated section in communication with the cavity, the male end being sized to fit within the internal cavity and having a D-shaped spring tab that deflects inwardly during initial insertion of the male end into the internal cavity, the tab and recess being sized such that when the male end is in the female end with the tab and recess aligned, the tab snaps radially outwardly into the recess to lock the two elongated sections together and the tab in the recess inhibits relative rotational movement between the tab and recess; wherein the tab has a straight trailing edge, a curved leading edge, and radially outward surfaces extending from the trailing edge to the leading edge, the radially outward surfaces having opposite straight side edges extending to an intermediate location from which the tab tapers radially inward to the curved leading edge such that the tab has a first specified side to side thickness from the trailing edge to the intermediate location. 2. The handle assembly of claim 1, wherein said recess extends from the cavity radially through the outer wall of the elongated section having the female end.3. The handle assembly of claim 2, wherein said male end has a reduced outer diameter relative to the majority of the elongated section comprising the male end.4. The handle assembly of claim 1, wherein said male end is hollow.5. The handle assembly of claim 1, wherein said male end includes a pair of slits extending in an axial direction to a terminal edge of the male end.6. The handle assembly of claim 1, wherein there are two such tabs on the male end, and two such recesses in the female end.7. The handle assembly of claim 1, wherein said female end has an axial groove extending from a terminal edge thereof to the recess.8. The handle assembly of claim 1, wherein said recess is D-shaped.9. The handle assembly of claim 1, wherein said tab extends radially less than the thickness of said recess into which said tab snaps.10. A handle assembly, comprising:an elongated grip section having an outer surface suitable to act as a handle, said grip section having a lower grip connector end; an elongated pole section having an upper pole connector end and a lower pole connector end; and an elongated accessory attachment section having an upper attachment connector end and a lower yoke structure having multiple arms for receiving an accessory; wherein said upper pole connector end and said lower grip connector end are configured such that the elongated pole section can be snap locked to the elongated grip section by axial relative movement between them, causing a tab on one of said sections to move radially outward into a recess in the other of said sections; and said lower pole connector end and said upper attachment connector end are configured such that the elongated pole section can be snap locked to the elongated accessory attachment section by axial relative movement between them, causing a tab on one of said sections to move radially outward into a recess in the other of such said sections and inhibit relative rotational movement between said tab and recess; wherein each said tab is D-shaped having a straight trailing edge, a curved leading edge, and radially outward surfaces extending from the trailing edge to the leading edge, the radially outward surfaces having opposite straight side edges extending to an intermediate location from which the tab tapers radially inward to the curved leading edge such that the tab has a first specified side to side thickness from the trailing edge to the intermediate location.
