Connector assembly for connecting pipes
Provided are connector assemblies for connecting pipes. For example, a connector assembly can include a connector formed with a hollow into which a pipe is inserted. A large diameter portion on at least one side of both end portions of the hollow where the large diameter portion is formed has a relatively large inner diameter and a housing space inside. The connector assembly also includes a ring-shaped sealing member provided in the hosing space and a grip member provided adjacent to the sealing member in the housing space. Further, the grip member has a body portion formed to contact an inner circumferential surface of the large diameter portion and a pair of sharp portions formed to be bent from both sides of the body portion and to partially bite into the outer circumferential surface of the pipe by crimping the outer circumferential surface of the large diameter portion.
