ABSTRACT:
The present invention is directed to a clamping apparatus for securing to and pulling upon an enlarged end of a longitudinal member of an automobile or vehicle chassis. The clamping apparatus has a pair of facing jaw members each having a bearing portion, a pulling portion, and an intermediate portion therebetween. The bearing portions each have a groove that cooperate to substantially surround the periphery of the longitudinal member perpendicular to its longitudinal axis such that the clamping apparatus may not slide off the longitudinal member, while the hearing portions bear upon the enlarged end as an axial pulling force is transferred from the clamping apparatus to the automobile chassis.
