Embodiments of the invention relate to connectors for connecting strips of light-emitting diodes (LEDs) end-to-end and for connecting a single strip of LEDs to a power source. The connectors define a compartment to receive a strip of LEDs. Tabs extending inwardly from the sides of the connector retain the strip. Electrical contact with the strip is made by a pair of spring clip contacts that bear against electrical terminals on the strip. A hinged lid has an opening positioned so as not to obstruct the last LED on the strip, and carries a downwardly-facing block that bears against the spring clip ends to keep them in contact with the terminals of the strip. In a strip-to-power connector, the connector defines one compartment for each conductor, and each conductor carries connecting structure. Ends of the spring clip connectors carry complementary connecting structure.
