Abstract: A cord clamp for a lampholder includes at least two tongue elements which are mutually, reciprocally and relatively movable, and between which a cord can be gripped with the aid of a clamping keeper member. The tongue elements are laterally movable in relation to each other, with their base arranged at an opening in the end portion of the lampholder. The base portion is in sliding engagement against the end portion, and the other free ends or top portions of the tongue elements are adapted to extend through an opening in a disc-shaped top portion of the clamping keeper member. The clamping keeper member further includes hooked snapping tongues projecting from the disc-shaped element which cooperates with complementarily formed locking grooves on the lampholder. The keeper member, in its position fully thrust over the tongue elements and the end portion of the lampholder, achieves a permanent snap fastening of itself as well as secure positional fixation of the cord in the lampholder.
