• a connector including a large diameter part having a hollow, into which a pipe is inserted, therein and in which at least any one of opposite ends of the hollow has a larger inner diameter such that an accommodation space is formed inside the one end of the hollow, and a pressing part continuously formed along a lengthwise direction of the large diameter part in a direction in which the pipe is inserted, having a smaller diameter than the large diameter part, and formed to surround an outer peripheral surface of the pipe;
• a ring-shaped sealing member provided in the accommodation space and surrounding the pipe on the outside of the pipe;
• and
• a grip member provided in the accommodation space to be adjacent to the sealing member,
• wherein at least a portion of the grip member presses an outer peripheral surface of the pipe in a condition in which an outer peripheral surface of the large diameter part is pressed.
