ABSTRACT:
A coupling particularly suitable for connecting hoses and pipes having a coupling head with an internal annular groove adjacent to its input opening and a locking means disposed within that annular groove for locking to a nozzle. The locking means comprises an elastic annular spring member which has a pair of counter directed annular spring arms that define a slot in the spring member. The arms encompass the coupling head while the spring member is disposed within the internal annular groove of the coupling head through a slot-like circumferential opening. The nozzle includes a cone formed on its circumference and an annular groove formed adjacent to the cone so that when the nozzle is inserted into the coupling head the cone will spread the elastic annular spring member allowing the spring member to be finally disposed around the annular slot within the nozzle. Several variations of the annular spring member are also shown.
