Abstract

The present invention relates to a power cord clamp for lamp holders with a support formed by a tube or stem, featuring very easy assembly, the power cord clamp comprising a body (1) having at least one elongated region (2) which can be inserted in the end of the tube or stem which is connected to the lamp holder, this region (2) being crossed longitudinally by a passage (3) for the electric power supply cord of the lamp holder. The body (1) has, in its region crossed by the passage for the cord, at least one portion (7a) which can flex towards or away from the longitudinal axis of the passage (3). This flexible portion (7a) has, on its side directed towards the passage (3), power cord clamping means which can engage the cord as a consequence of the flexing of the portion (7a) towards the axis of the passage (3) caused by the engagement of the outer surface of the flexible portion (7a) against the inner surface of the tube or stem when the elongated region (2) is inserted in the tube or stem during the assembly of the lamp holder.
