ABSTRACT:
A quick release pipe connection includes a first connector and a second connector detachably combined with the first connector. The first connector includes a first connector seat, a first connecting member, a locking member, a limit pin, a first support member, a first elastic member, and a first stop member. The second connector includes a second connector seat, a second connecting member, a second support member, a second elastic member, and a second stop member. Thus, the first connector is combined with the second connector by inserting the second connecting member into the first connecting member, and the second connector is detached from the first connector by pressing the press portion of the locking member, so that the pipe connection is assembled and disassembled easily and rapidly.
