An improved hand held drain cleaning apparatus is disclosed which is of the type employing a flexible snake which is rotated and inserted into a waste line to remove blockage. The apparatus includes a housing in which the sanke is coiled and a guide tube extending from the housing and through which the snake passes for insertion into a waste line. A manually actuated sleeve assembly is provided on the guide for displacing resilient spring finger clamping elements into engagement with the snake to hold the snake against axial displacement relative to the housing during insertion and/or removal of the snake from the waste line and to clamp the snake against rotation relative to the guide tube and the housing during the drain cleaning operation. The sleeve assembly is removably retained on the guide tube, and the spring finger elements, the guide tube and the sleeve assembly engage with one another to alone removably support the spring finger clamping elements against axial and circumferential displacement relative to and radial separation from the guide tube. Upon removal of the tubular hand grip, the spring finger gripping elements are released for separation from the guide tube.
