A spring clamp with a lower clamping jaw, an upper clamping jaw, a first handle portion extending rearwardly from and integrally connected with the lower clamping jaw, a second handle portion extending rearwardly from the upper clamping jaw, the upper clamping jaw having a slide-housing integrally connected to the second handle portion, and an L-shaped bracket having a first leg portion having a free end for sliding cooperation with the slide-housing and a second leg portion extending at right angles to another end of the first leg portion.

The L-shaped bracket may be oriented in two different states so that smaller and larger workpieces may be accomodated and clamped between the second leg portion and the lower clamping jaw. In the first state, the free end of the first leg portion faces away from the lower clampi…
