摘要： A molded, thermoplastic outlet box is provided with openings near the back wall and clamp arrangements inside the openings. Each clamp arrangement includes a swingable clamp arm having teeth at the end thereof which cooperate with teeth formed on an inner wall of the box to engage a cable which has been inserted. An abutment prevents the clamp arm from swinging inwardly until a predetermined force has been exceeded. Flexibility of the arm is enhanced by parallel slots extending away from the opening on opposite sides of the clamp arm.
