Abstract: The present disclosure is related to an improved connector for use in electrical ornamental articles mainly disposed on Christmas trees or the like, which has an integrally formed plastic shell made by injection molding with three consecutive sections, the first thereof being in trapezoid form, and the second and third being of cylindrical shape with different size. The tapered sides of the trapezoid section permit easy attachment of the connector to a socket; on the external wall of the second section are disposed a plurality of spaced collapsible ribs in the axial direction. Metallic contacts are removably placed in a pair of divided tunnels of the connector with the front ends thereof extended out of the connector and reversely bent in abutment against the external wall of the first section.
