A pipe coupling assembly may include a male coupling component including a tubular member having a retaining ring projecting radially from, and extending around a portion of the circumference of the tubular member. A female coupling component may include a body having a bore with a first end sized to slidingly receive the first end of the tubular member. An O-ring may be at least partially received in a radial groove formed in a side wall of the bore, and may be sized to sealingly engage an exterior of the tubular member when the tubular member is received within the bore. The body may also include a retaining pad extending outwardly relative to the bore, and spaced from the first end of the bore to define a channel between a first end of the body and the retaining pad that is sized to at least partially receive the retaining ring.

Connecting device for a fluid supply system including a female connecting part and a male connecting part, wherein the female connecting part has a back support plate; a middle support plate; a front support plate; wherein the front support plate comprises a fluid outlet port intended to be connected to a corresponding connecting element of the male connecting part, and the back, middle and front support plates each comprising an outlet hole connected to the outlet port, wherein the middle support plate is fastened to the back support plate and the front support plate is fastened to the middle support plate; wherein the front support plate is configured to be able to move along a first axis, wherein the middle support plate is configured to be able to move along a second axis, the second axis being transverse to the first axis.

A push type locking structure for pipe couplers includes a coupling pipe externally provided with a recess having a pair of pipe pivotal holes formed on two side walls thereof and having a radially penetrated receiving hole formed at a first end thereof to communicate with a passage defined in the coupling pipe; a push member including a pair of first pivotal connection sections and a second pivotal connection section; a hollow push retaining member received in the receiving hole on the coupling pipe; and a spring disposed between the recess and the push member. The push member is pivotally connected to the push retaining member and the coupling pipe by two shafts extending through the first and the second pivotal connection section. When the push member is pushed downward, the push retaining member is moved upward radially to unlock a pipe from the coupling pipe to move axially.
