Buckle assembly

A socket device for receiving a plug having a flexible plate with a locking lug in a plug and socket type buckle assembly, comprising:

• a top part having an outside surface and an inside surface;
• a flexible release button integrally formed with said top part and having a downwardly projecting tip;
• at least one projecting ledge disposed on the inside surface of said top part for engaging one side of the locking lug when the plug is inserted in said socket device;
• a bottom part integrally formed with said top part and having an outside surface and an inside surface, said top and bottom parts defining a cavity for insertion of said plug;
• and
• a flexible tongue integrally formed with said bottom plate, said tongue having means for engaging an opposite side of the locking lug when the plug is inserted in said socket device,
• wherein downward pressure on said release button when said plug is inserted in said socket device disengages the locking lug from said projecting ledge, and further downward pressure on said release button bends the flexible tongue and releases the locking lug from the flexible tongue to remove said plug from said socket device.

A plug device for inserting into a socket in a plug and socket type buckle assembly, comprising:

• a base;
• a flexible plate integrally formed with said base and having two flat surfaces and a free end;
• and
