This pump clamp adapter allow an individual who has a can or a pail that has a spout with a annular rim around the opening to be used with a safety pump. The adapter is created out of two semi-circular disk. Around the outer edge of the semi-circular disk on its bottom is a ridge. When the two semi-circular disks are placed together to form a cylindrical disk the ridge forms an annular recess underneath the disk. This annular recess fit over the annular rim adapter on the can. On the bottom of the ridge are three wedge shaped feet. These wedge shaped feet are designed to scratch through the paint on the top of the can and make contact with the metal below said paint. A semi-circular's cut out is formed in the center of the straight side of the semi-circular's disk. When the two semi-circular's disks are placed together, the semi-circular's cut out will form a bore in the center of the cylindrical disk of sufficient size so that a pump can be placed through the bore. On the upper inside edge of this ridge on the straight portion of the semi-circular disk a shoulder is formed extending outward from the ridge. This shoulder is adapted such that when the ridges are tighten together the lower portion of the semi-circular disk without the shoulder will draw in further then the upper portion. Thus, causing the feet on the annular ridge to dig into the painted surface of the can.
