Tube connector

Claim 1

A tube connector comprising a cylindrical socket for mounting in a hole in a plate or the like, said socket having external means for keying said socket in said hole in a predetermined position, said socket further having resilient retainer means for snapping through said hole to retain said socket in said plate or the like, said socket further having adjacent an upper edge thereof a resilient circumferential flange of frusto-conical configuration for resiliently bearing against a face of said plate or the like opposite said retainer means, and said socket further having a hollow core with a transverse lower wall, said well having a regular polygonal aperture with a predetermined number of sides therethrough, and a connector interfitting with said socket and including a lower cylindrical portion, an upper cylindrical portion upsatnding from said lower cylindrical portion, a lateral tubular portion extending from said lower cylindrical portion, said upper and lower cylindrical portions and said lateral tubular portion having a continuous bore therethrough, a lateral resilient flange of frusto-conical configuration resiliently engageable with said wall of said socket from an underside thereof, a polygonal portion complementary to said polygonal aperture and of said predetermined number of sides disposed adjacent said lateral resilient flange, and a plurality of vertical resilient walls above said polygonal portion and extending radially from said upper cylindrical portion, said walls being of said predetermined number and equally arcuately spaced so that said walls are respectively spaced midway between apices of said polygonal portion, said connector being axially insertable into said socket through said socket wall with said walls directed toward the apices of said aperture in said socket wall, and thereafter turnable to dispose said polygonal portion complementarily in said polygonal aperture with said walls disposed against an upper surface of said socket wall.
