A small form-factor pluggable metal cage has two sidewalls, a sidewall cover, a top plate, a soleplate and rear cover, which are made of a single piece of metal plate. Two types of legs extend from the cage, one being compliant type for extending through the board holes defined in a printed circuit board (PCB) and the other being piggy type abutting against the board. The compliant legs define two arc sections for stability and preventing the cage from disengaging from the PCB during the course of reflowing. The rear cover includes an inner panel extending from the second sidewall with a tab formed on a free end to engage a notch defined in the first sidewall. An outer panel extends from the top plate. The outer panel defines a slot for engaging a clasp of the inner panel. Two patches respectively extend from the sidewalls and are located above the inner panel.
