Abstract
A plastic spring for each end of a tubular carrier, or magazine, used to transport integrated circuits, especially ceramic IC's, to secure them against sliding or chipping within the tube is formed with a finger grip, or stop pin end and an opposite IC contacting end, the ends being joined by a plurality of integral sections of flexible, resilient elastomeric material of rhombus, or diamond, shape joined along the longitudinal center line by integral webs to form a one piece, flat, thin body of uniform outside depth and width and fitting in the space between the upper and lower parallel walls of the tubular carrier. The spring is preferably carbon conductive to avoid static build-up.
