A connector system includes a first connector body defining a channel between a longitudinally-oriented fixed wall and a longitudinally-oriented flexible beam. The flexible beam is located opposite and generally parallel to the fixed wall when in a relaxed state. A distal surface of the flexible beam defines a first protrusion having a first inclined surface. A second connector body defines a cavity configured to receive the first connector body. A mesial surface inside the cavity defines a second protrusion having a second inclined surface configured to engage the first inclined surface of the flexible beam when the connector bodies are mated. A member inserted into the channel causes the flexible beam to flex laterally and move the first inclined surface with respect to the second inclined surface sufficient to generate a longitudinal force between the first and second inclined surfaces and thus between the first and second connector bodies.
