Abstract
A tubular plastic body of a neon tubing support has a bore terminating in a lower opening and in an opposite internally shouldered upper opening. A helical spring is installed in the bore through the lower opening and retained by a plug in the lower opening at one end of the bore and by the shoulder at the other end. A stem unit includes a shaft having a tubing engaging element on one end, and extends into the bore coaxially with the spring and terminates in an integral bulbous portion. The bulbous portion is axially slotted to define legs which can flex toward each other for clearing through the undersized top opening in the body. The bulbous portion has a shoulder and passes axially through the spring to compress some of the convolutions for developing a force causing the shoulder to engage with the convolutions intermediate of the ends of the spring to create a bidirectionally resilient neon tubing support.
