    Patent number: 6851698
    Abstract: A coupling member 2 is brought into a mouth 23 to contact a camming surface 61 of an engagement member 60. The member 60 rotates clockwise to bring the securement means 50 up to retain the coupling member. A camming surface 62 of the engagement member 60 contacts surface 72 of a restrictor 70 to cause the restrictor to first move anticlockwise and then to drop back in a clockwise direction to trap the engagement member in position and to prevent the securement means 50 from allowing the coupling member 2 to be released.
