Title:
CONNECTOR
Document Type and Number:
WIPO Patent Application WO/2021/171871
Kind Code:
A1
Abstract:
This connector connects to a first pipe having a bulge section. The connector comprises a retainer. The retainer can move between a standby position at which insertion and removal of the first pipe is permitted, and a restriction position at which removal of the first pipe is restricted. The retainer comprises a fixing leg and a biasing leg. The fixing leg has a fixed section that is fixed to a connector body when the retainer is in the standby position and when the retainer is in the restriction position. The fixing leg moves radially outward upon contacting the bulge section, thereby releasing the fixation of the fixed section. The biasing leg elastically deforms radially outward upon contacting a distal end section of the first pipe located more toward the distal end side than the bulge section, thereby biasing the retainer in the direction toward the restriction position.
