Abstract An embroidery hoop includes a plastic inner ring element, a plastic outer ring element having a body with a gap therein, and means for adjusting the diameter of the outer ring element. The adjusting means takes the form of first and second parts, each of which is more massive than the body of the outer ring element. One of the parts is integral with the portion of the body situated on each side of the gap. The parts are provided with registering lateral apertures and are adjustably positionable relative to each other by a screw and nut assembly. The screw is received in the apertures of both parts and has a head portion located on the exterior side of the first part. A threaded portion adopted to engage the nut is situated on the exterior side of the second part. The screw is provided with a knurled portion fitting tightly within the interior of the aperture of the first part and effective to prevent rotation of the screw relative to the parts.
