A pinch-grip hanger includes an elongated body with first and second pinch-grips positioned along the body. Each pinch-grip has a stationary back leg and a front leg movable about a pivot axis, with single gripping portions at the lower ends thereof. An inverted U-shaped spring applies a force near the lower ends of the legs to bias the gripping portions thereof toward each other. Moving the upper ends of the front leg rearwardly separates the gripping portions, thereby opening the pinch-grip. Spacers at opposite sides of the legs extend in the front-to-back direction a sufficient distance so that contact with another hanger on a rack will not move the upper ends of the legs toward each other a sufficient distance to release an item being held by the gripping portions. Opposed overlapping barriers extend from the front and back legs just below the pivot axis. These shield an item held by the hanger from the area near the pivot axis. The gripping portions each have a single gripping tooth, the tips of which are substantially in contact when the pinch grip is closed and an item is not being held by the hanger. The teeth have substantially planar parallel upper surfaces that together define the lower end of the gripping area between the gripping portions. The gripping portions also have outwardly tapering end portion with substantially smooth surfaces extending downward below the teeth.
