A male tab terminal has an O-ring mounting portion formed between its wire connection portion and its electrical contact portion, and this O-ring mounting portion is surrounded by an opening peripheral surface of an O-ring receiving step portion of a female connector housing which defines an opening of a male terminal receiving chamber. An O-ring, mounted on the O-ring mounting portion of the male tab terminal, is held in intimate contact with an outer peripheral surface of the O-ring mounting portion over an entire periphery thereof, and also is held in intimate contact with the opening peripheral surface of the O-ring receiving step portion over an entire periphery thereof. When a female connector and a male connector are fitted together, the O-ring is directly clamped between the female connector housing and a male connector housing in a direction of fitting of the female and male connectors, and is pressed by the two connector housings.

What is claimed is: 1. A connector comprising a female connector, and a male connector for fitting to said female connector, one of said female and male connectors including: a connector housing; a male terminal receiving chamber formed in said connector housing; a male terminal including a wire connection portion for electrical connection to a wire, and an electrical contact portion which is electrically connected to a female terminal in another of said female and male connectors when said female and male connectors are fitted together, said male terminal being received in said male terminal receiving chamber such that said electrical contact portion of said male terminal projects outwardly from said male terminal receiving chamber through an opening of said male terminal receiving chamber; a receiving step portion which is formed in said connector housing, and has an opening peripheral surface defining said opening; a mounting portion which is formed on said male terminal, and is disposed between said wire connection portion and said electrical contact portion, and is surrounded by the opening peripheral surface of said receiving step portion; and an annular elastic seal member which is clamped between said mounting portion of said male terminal and the opening peripheral surface of said receiving step portion; and wherein said elastic seal member is held in intimate contact with an outer peripheral surface of said mounting portion over an entire periphery thereof, and is held in intimate contact with the opening peripheral surface of said receiving step portion over an entire periphery thereof, and when said female connector and said male connector are fitted together, said elastic seal member is directly clamped between said connector housing and a connector housing of said another connector, receiving said female terminal, in a direction of fitting of said female and male connectors, and is pressed by said two connector housings. 2. A connector according to claim 1, wherein when said female connector and said male connector are fitted together, said elastic seal member is directly pressed by a peripheral surface of the opening peripheral surface of said receiving step portion, which is disposed close to said male terminal receiving chamber, and intersects a direction of extending of said electrical contact portion of said male terminal and a portion of a front surface with respect to the fitting direction of said connector housing of said another connector, which is disposed around a male terminal insertion port which allows said female terminal and said electrical contact portion of said male terminal to contact each other formed. 3. A connector according to claim 1, wherein the outer peripheral surface of said mounting portion has curved surface portions. 4. A connector according to claim 1, wherein said mounting portion has generally U-shaped grooves, and said elastic seal member is fitted in said U-shaped grooves, and is retained by said grooves. 5. A connector according to claim 4, wherein a bottom surface of each of said U-shaped grooves in said mounting portion defines said curved surface portion. 6. A connector according to claim 1, wherein said elastic seal member is an O-ring made of rubber. 7. A connector according to claim 1, wherein a waterproof plug is disposed between the wire, connected to said wire connection portion of said male terminal, and said connector housing of said one connector, and said waterproof plug and said elastic seal member cooperate with each other to make said male terminal receiving chamber watertight.
