Patent abstract
A male housing (30) has a tubular part (32) with inner and outer tubes (36, 37) separated by a groove (38). A female housing (10) has a fit-in portion (14) to be fit in the inner tube (36). A seal ring (18) is mounted on the fit-in portion (14) and is compressed between opposed surfaces of the fit-in portion (14) and the outer tube (37). Loosening prevention portions (19) on the fit-in portion (14) fill a gap between the opposed surfaces of the fit-in portion (14) and the inner tube (36) and prevent both housings (10, 30) from being radially loosened.
