Abstract
Retainer assembly has a pair of retainers that are disposed on diametrically opposite sides of a passage way of an annular engaging projection of a pipe, and release arms that are provided on the retainers, respectively. Each of the retainers has a fixing end portion integrally connected to and supported by a pipe retainer portion, and a free end including an engaging portion for snap-engaging with the annular engaging projection. Each of the release arms has a cross-sectional shape for allowing a pressure on the release arm in a longitudinal direction, when being pressed radially inwardly from outside.
