ABSTRACT:
A coupling assembly entirely formed from plastics material is provided for selectively connecting and disconnecting first and second fluid lines. A male coupling member includes an external groove that receives a radially inward extending shoulder of the sleeve. An external groove on a female coupling member is selectively engaged by latching tabs extending radially inward from the sleeve. The latching tabs are selectively pivoted radially outward through depression of release buttons. The pivoting action of the latching members is defined along a central portion in which circumferential strips undergo a twisting action.
