A plug connector for latching into a receptacle cage with a pair of resilient inwardly extending locking tabs, comprising:

• a housing defining opposite top and bottom walls in a first direction and a pair of opposite sidewalls in a second direction perpendicular to said first direction to commonly defining a receiving space with a mating port located in a front portion of the receiving space, said top wall defining a first flange and said bottom wall defining a second flange, said first flange being smaller than said second flange in the second direction;
• a releasing mechanism attached to the housing and back and forth moveable relative to the housing along a third direction perpendicular to both said first direction and said second direction, said releasing mechanism defining at least one actuating arm located upon one of the sidewalls.
