A contact is provided for use in an interface connector. The contact comprises a contact beam 12 having a mating surface proximate a first end of the contact beam. The mating surface 16 is configured to join a contact pad, such as on a module board to carry high speed data signals therebetween. The contact further includes a tail portion configured to join a contact pad, such as on a host board. A leg portion of the contact joins and interconnects the tail portion and a second end of the contact beam. The leg portion includes a retention segment, through which a signal transmission path passes as data signals are carried through the leg portion between the tail portion and contact beam, thereby reducing signal degradation. The retention segment is configured to secure the leg portion within a connector.
