Abstract
Abstract A clamp for fastening trim or protective strips on support surfaces which includes a single strip of sheet metal formed to three spaced, superposed legs, the outer legs being connected by a bridge, and the middle leg bent inwardly from the free end of the lower outer leg and extending toward the bridge and between the outer legs. The lower leg and bridge are slotted to slide or plug onto a shank of a T-shaped stud, the lower and middle leg clamping the top and bottom of the head of the stud. The upper and middle legs clamp a projection on the trim strip.
