The latch (10) is secured to the rear side (118) of the panel (12) and comprises a base plate (60), a bar lock (62), a plug lock (64) and a retainer (68). The base plate includes a bar lock guide (70), a plug lock guide (78) and an opening (76) extending through the back wall (72) of the base plate (60). The bar lock (62) is slidably mounted in the bar lock guide (70) and has a lateral notch and a rearwardly-projecting first hook (90) engaging the opening (76). The plug lock (64) is rotatably mounted in the plug lock guide (78) and includes a tab (106) engaging the lateral notch (88). The retainer (68) is rigidly secured to the back wall (72) of the base plate (60).
