Abstract
A steering column has an upper column section and a lower column section with an intermediate collapsible tubular member in torque transmitting engagement with the upper and lower column sections. Each column section has an end telescoping into the tubular collapsible member. Each end is square in cross-section with one end having a slightly larger cross-sectional area than the other such that the smaller one is received therein and prevents free relative rotation of the two column sections if the collapsible member is ruptured.
