A connector is described that includes a housing (30, FIG. 1 ) with a latch (34, 36) at each end which can project through a corresponding hole (20, 22) in a circuit board to releasably hold the connector to the board. Each latch has a largely U-shaped arm (40) with a pair of largely parallel arm parts (42, 44) joined by a lower part (46). The arm parts are biased apart but can be resiliently deflected together to pass the lower portion of the arm into a circuit board hole (20), until an upwardly-facing shoulder (50) on one of the arms snaps below the lower face of the circuit board to prevent removal of the latch. The latch can be removed by squeezing the arm parts together so the part forming the shoulder (50) can be pulled up through the hole. The shoulder has a far edge which lies further from the other arm part, with the far edge having a radius of curvature no more than about twice the radius (R) of the circuit board hole, to provide a shoulder of large area while enabling the shoulder to pass through the hole with only moderate squeezing together of the arm parts.
