An electrical connector configured to be mounted on a substrate, comprising: a connector housing including a housing body that defines an opening configured to receive at least one complementary electrically conductive component along a mating direction, the housing body defining a mating interface and a mounting interface which are oriented substantially perpendicular with respect to each other, wherein the housing body includes a top end and an opposed bottom end that is spaced from the top end along the transverse direction, the bottom end defining the mounting interface that is configured to be mounted to the substrate; a contact assembly formed by first and second contact members (112, 114) spaced apart from each other along a lateral direction, supported by the connector housing and configured to contact the complementary electrically conductive component when the complementary electrically conductive component is received in the opening, the lateral direction being perpendicular to the transverse direction and to the mating direction; wherein each of the first and second contact members (112, 114) includes a first contact body including a first intermediate portion, a first end portion that extends forward along the mating direction from the first intermediate portion, and an arm that extends forwards along the mating direction from the intermediate portion, the arm having a proximal portion, a distal portion, and an intermediate portion between the proximal and distal portions, characterized in that the connector housing further comprises a retention rib monolithic with the housing body, extending between the top end and the bottom end along the transverse direction of the housing body, wherein the intermediate portions of the arms of the first and second contact members (112, 114) are spaced outward in the lateral direction with respect to each of the proximal and distal portions, and the intermediate portions of the arms of the first and second contact members (112, 114) frictionally bear against the retention rib so as to retain the respective contact member with respect to the connector housing. a connector housing including a housing body that defines an opening configured to receive at least one complementary electrically conductive component along a mating direction, the housing body defining a mating interface and a mounting interface which are oriented substantially perpendicular with respect to each other, wherein the housing body includes a top end and an opposed bottom end that is spaced from the top end along the transverse direction, the bottom end defining the mounting interface that is configured to be mounted to the substrate; a contact assembly formed by first and second contact members (112, 114) spaced apart from each other along a lateral direction, supported by the connector housing and configured to contact the complementary electrically conductive component when the complementary electrically conductive component is received in the opening, the lateral direction being perpendicular to the transverse direction and to the mating direction; wherein each of the first and second contact members (112, 114) includes a first contact body including a first intermediate portion, a first end portion that extends forward along the mating direction from the first intermediate portion, and an arm that extends forwards along the mating direction from the intermediate portion, the arm having a proximal portion, a distal portion, and an intermediate portion between the proximal and distal portions, characterized in that the connector housing further comprises a retention rib monolithic with the housing body, extending between the top end and the bottom end along the transverse direction of the housing body, wherein the intermediate portions of the arms of the first and second contact members (112, 114) are spaced outward in the lateral direction with respect to each of the proximal and distal portions, and the intermediate portions of the arms of the first and second contact members (112, 114) frictionally bear against the retention rib so as to retain the respective contact member with respect to the connector housing.
