PCT No. PCT/US92/02083 Sec. 371 Date Apr. 15, 1992 Sec. 102(e) Date Apr. 15, 1992 PCT Filed Mar. 13, 1992 PCT Pub. No. WO93/18560 PCT Pub. Date Sep. 16, 1993.A holdown key (40, FIG. 5) is provided that holds a low profile connector housing (30) to a circuit board (16), which securely holds the key to the connector before installation in the circuit board, and which provides high retention in the circuit board with only moderate stress on the key material. The key has a pair of largely vertically-extending legs (60, 62) with lower ends that merge and with upper ends that are free of each other but which have locations (80, 80a) that abut each other when the legs are deflected toward each other. When the key is installed in a slot (50) of the connector housing, the legs are preferably deflected partially towards each other so the gap (B) between the locations is less than initially, but is not zero. However, when the key is fully installed in the circuit board, the locations abut each other to close the gap (C) and provide large retention force in the circuit board. Each leg has upper and lower shoulders (100, 104) that abut upper and lower surfaces (102, 106) on the connector housing to retain the key in the housing.
