A protector to prevent opening of doors of adjacent vehicles from denting a car door is disclosed. The protector has a hollow outer tube which may be shortened to proper size to fit the door. In cross-section, the tube has a rounded protuberance on its outside and a curved bottom with outward extending feet to prevent the tube from turning once it is applied. Within the outer tube is a highly resilient core of rubber or plastic material (also capable of being cut to a length less than the width of the car door) and hooks are screwed into the ends of the core. The hooks engage the vertical side edges of the door to hold the protector in place. Alternatively the protector may be formed of a single piece of resilient rubber or plastic material which may be cut to size and hooks screwed into the ends.
