The underbody clamping device for work pieces comprises a box-shaped body for supporting a movable clamping member, the clamping member in turn comprising a fore hook-shaped portion which extends outwardly from the box-shaped body, and a rear shank. The device also comprises a drive member tiltably supported by the box-shaped body, operatively connected to the shank of the clamping member by a hinge axis; the device further comprises guide means for guiding the clamping member, which include first and second arch shaped slots in the rear shank, and first and second guide pins secured to the box-shaped body which extend respectively into the first and into the second arch shaped slots, the arch shaped slots being conformed and arranged to cause the clamping member to move parallel to the longitudinal axis of the body, along an arched path corresponding to a rotational path of the hinge axis of the tiltable drive member.
