1. A cage-nut for use with a panel having a blind bore therein, said cage-nut comprising: a one-piece generally U-shaped cage for insertion base end first into said bore, said cage comprising a base having an aperture therein and two generally semi-circular arms folded concave side-to-concave side to define a caged nut receiving cavity substantially coaxial with said aperture, said arms defining an axially extending pair of slots between the opposed edges of said arms along a portion of their axial extension, each arm having an axially extending tongue attached at the end closest the base, the free end of the tongue bent outwardly to form an outwardly extending barb and the portion of the tongue between the free end and the attached end being bent inwardly to extend into the caged nut receiving cavity at a point axially coincident with a portion of said axially extending slots, said base including a pair of radially outwardly extending wings thereon to prevent rotation of saiD cage in said bore; and a caged nut received in said caged nut receiving cavity, said caged nut having a pair of projections on the periphery thereof for receipt in and cooperation with said axially extending slots to allow axial movement of said nut along said axially extending slots while rotationally fixing said nut to said cage, said tongues biasing said caged nut to the axial portion of said slots closest said base, said nut upon axial movement in said slot towards the free ends of said arms being effective to force said tongues out of said cavity and to force said outwardly extending barbs into said blind bore.

2. The cage-nut of claim 1 wherein said slots are defined by the spaced edges of said arms, each arm having an enlarged portion at the free end thereof which will extend towards the other arm to define the axial boundary of sid slots.

3. The cage-nut of claim 2 wherein said barbs may be forced into said bore prior to movement of said nut by means of an object inserted into said caged nut receiving cavity.

4. The cage-nut of claim 1 wherein said tongue extends into said cavity at a point axially coincident with the portion of the slots nearest the free ends of the arms.
