A threadless pipe coupling (x00) comprises a socket (x01), a plug (x02) configured for being inserted into the socket (x01) in an insertion direction (10), a sealing member (x03) arranged between a circumferential outer surface (x04) of the plug (x02) and a cooperating inner surface (x05) of a circumferential side wall (x06) of the socket (x01), so as to provide a fluid tight seal when the plug (x02) is placed in the socket (x01), wherein the plug (x02) is retained in the socket (x01) by means of a locking member (x07) inserted in a transverse direction through a slot (x08) in the circumferential side wall (x06) of the socket (x01) to engage around the plug (x02) at a location behind the sealing member (x03) as seen in the insertion direction (10). The ends (x28, x29) of the locking member (x07) in the mounted position are located between the outer surface (x04) of the plug (x02) and the circumferential side wall (x06) of the socket (x01) as seen in a radial direction.

The present invention provides an overhead shower head, which needn't a wrench when assembled and disassembled, the overhead shower head comprises a shower head main body and a universal ball disposed in a ball fixing seat at the rear side of the shower head main body; wherein an abutting fitting portion is disposed between the universal ball and the ball fixing seat, when the universal ball and the ball fixing seat rotate relatively, the abutting fitting portion abuts in the rotating direction, so that the universal ball and the ball fixing seat rotate together. The assembly and disassembly of the overhead shower head of the present invention can be achieved by just rotating the shower head main body without using tools such as a wrench, the assembly is fast and convenient.

A pressure washer coupler is provided between the wand and spray nozzle of the pressure washer so that the angle of the spray can be selectively set. The coupler includes male and female quick connectors for the wand and the spray nozzle. A spring biased detent assembly allows one end of the coupler to be rotated 360 relative to the other end of the coupler, with the detent assembly maintaining the ends in a selected position. Thus, the spray can be directed parallel or perpendicular to the wand axis, and to numerous orientations therebetween.

A spherical decoupler conduit for connecting misaligned components, and a method for making the same, where the spherical decoupler includes an inlet connection with a first spherical portion; an outer slider with a second spherical portion for pivotably mating with the first spherical portion and a tubular portion; an inner slider having a tubular portion in a telescoping relationship with the tubular portion of the outer slider and a third spherical portion; and an outlet connection with a fourth spherical portion for pivotably mating with the third spherical portion.

A quick-connect and rotatable tube connection comprises a male connector with tiered outer teeth and a female connector with tiered internal annular grooves, which hold the teeth and allow their movement within the grooves. Each groove includes a groove-wall that features cross-channels, enabling the teeth to pass through and enter adjacent annular grooves. Through relative coaxial rotation, aligning or misaligning the teeth with the cross-channels, combined with axial pushing or pulling actions, the connectors engage or disengage. The last annular groove features a stop-wall to limit the maximum axial engagement of the connectors. A locking mechanism with corresponding elements on both connectors restricts their relative rotational movement and prevents disengagement of the tube connection by blocking the alignment of the teeth and cross-channels.
