Abstract
An assembly for adjustably supporting a luminous tube of a neon sign comprising a clamp post having a C-shaped end portion for frictionally engaging and retaining an outer surface of a luminous tube therein, a tubular column telescopically receiving the clamp post into one end thereof for movement along the longitudinal axis of the column, a ball-shaped portion on the other end of the column engageable in a semi-spherical socket of a base for positional adjustment of the column and clamp post within a 360.degree. circle of movement, and means on the base for frictionally gripping a support member to provide positional adjustable support of a luminous tube in spaced relation therefrom. The clamp post, tubular column, and base are preferably formed of molded plastic and engage in snap-fit relation. Spring means are provided in the tubular column to bias the clamp post against movement along the longitudinal axis of the column.
