- an elastic seal element fit around the outer periphery of a housing portion within a hood of said male electric connector housing, formed of a tubular portion and a flange portion in a tubular section so as to seal the gap between said male electric connector housing and a female electric connector housing which abuts against the outer periphery of said tubular portion so as to be inserted into said hood of said male electric connector housing; and
tongues harder than said seal element, fixed to a plurality of portions on the outer periphery of said flange portion of said seal element so as to protrude from the outer periphery of said flange portion, said tongues being retained by means of flexible arms arranged within said hood of said male electric connector housing, placed corresponding to the respective positions of said tongues when said seal element is fully inserted so as to abut against a wall of said male electric connector housing.

Abstract
A waterproof electric connector seal member includes a rubber-formed seal element having a rectangular tubular section and plastic-formed tongues fixed to a flange portion of the seal element. The seal member is retained in an electric connector housing via the tongues. Thus, although the shape of the seal element varies depending upon the number of terminals accommodated within the electric connector, the standard-shaped tongues can be commonly used.
