Abstract: The connector of this invention can make an arcless connection between an electric cable and a metallic object. The connector preferably is a C-clamp having a pair of opposed legs. One leg carries an adjustable clamp screw. The other leg carries a block of compressible, insulated, elastic material having a contact surface. At least one contact member has a portion thereof completely embedded in the block. The contact member has a sharply pointed tip adjacent to and facing the contact surface. By tightening the clamp screw against the metallic object, the clamping pressure will compress the block material until the pointed tip pierces the contact surface and establishes a forced electric connection between the contact member and the metallic object.
