ABSTRACT:
To substantially reduce the stock of spring cramp sizes needed for holding and clamping axle springs of motor vehicles having widely varying diameters, the clamping jaws of a spring cramp have a contact surface which is substantially flat and, at least in the zone of median plane of the jaw and over the entire jaw leg leading in the clamping direction, slightly slanting inwardly by an angle .alpha. of from 2.5.degree. to 6.degree., so that the radially outer edge of jaw leg trails behind the inner one during a clamping operation. In addition, a backing rib is provided projecting substantially symmetrically from the inner edge of each clamping jaw axially in the clamping direction, which rib extends through a center angle .beta. of from 30.degree. to 100.degree.. At their free ends, the jaw legs are about 1.5 to 2 times wider than in the zone of their median plane.
