The male member hood (20) surrounds the periphery of the rod-shaped male member (10), an annular portion which female connector is inserted (21), the annular portion so as to protrude toward the male element provided the includes a pair of claws (22) facing each other, provided in the annular portion, a pair of pressing portions for the pair of pawls are opposed in a direction perpendicular to the direction opposite the (23). When applying a pushing force F of the direction in which the pair of pressing portions (23) approach each other to the pair of pressing portions (23), the annular portion (21) is elastically deformed as a pair of claws (22) are separated .オス部材用フード(20)は、棒状のオス部材(10)の周囲を取り囲み、メスコネクタが挿入される環状部(21)と、環状部に、オス部材に向かって突出するように設けられた、互いに対向する一対の爪(22)と、環状部に設けられた、一対の爪が対向する方向と直交する方向に対向する一対の押圧部(23)とを備える。一対の押圧部(23)が互いに接近する向きの押力Fを一対の押圧部(23)に印加すると、一対の爪(22)が離間するように環状部(21)が弾性的に変形する。
