The present invention relates to a novel locking hose clamp device. The device is designed to function as a locking nut and remain tight. The device comprises a lock washer and an insert component. The device can be applied to a clamp and secured with a screw. The insert component is positioned around the screw, such that the screw is threaded into the insert component. The locking washer is secured around the screw, behind the head of the screw. When the user tightens the device, the screw threads catch onto corresponding threads within the insert component. The screw is threaded into the insert component and tightened down, such that the head of the screw contacts an edge of the insert component. The locking washer is then compressed which causes the screw to lock in place.

A sprinkler configured for engagement with a coupling, the sprinkler includes a raised lip end, the sprinkler defining a raised lip at the raised lip end; and a deflector end disposed opposite from the raised lip end, the sprinkler defining a groove between the raised lip and the deflector end.

Disclosed is a pipe coupling or a pipe clamp which has an outer clamp band with an outer longitudinal slot, an inner clamp band with an inner longitudinal slot and a tensioning mechanism arranged on the outer clamp band. The inner longitudinal slot is offset in relation to the outer longitudinal slot. A separate flat spanning element is provided on the inner clamp band in order to span the inner longitudinal slot. The spanning element extends from one side of the inner longitudinal slot towards the other side of said longitudinal slot.

A pipe coupling for coupling a first pipe to a second pipe wherein a gap exists between a first pipe end and a second pipe end. The pipe coupling includes a tubular insert configured to fit within the gap and match an inside diameter and outside diameter of the pipes, thereby providing a through-butt joint between the insert and the pipes. The pipe coupling also includes a half-tubular first fitting section and a half-tubular second fitting section, configured to snap-lock and form a tubular shape over the insert, the first pipe end and the second pipe end. In some embodiments, the insert is integral with the fitting sections.

A split coupler, and methods of making and using such a split coupler, whereby the split coupler includes a first semi-cylindrical member, a second semi-cylindrical member, and an interlocking assembly configured to interlock the first and second semi-cylindrical members to form a substantially cylindrical coupler having a coupler inner surface which defines a throughbore. Additionally, the split coupler can include spiral threads coupled to the coupler inner surface. Furthermore, the split coupler can include a flange inwardly extending from the coupler inner surface.

A three-way clamp includes a first clamp shell and a second clamp shell capable of being connected to or detached from each other. Each of the first clamp shell and the second clamp shell includes three engaging portions. The engaging portion includes an accommodating cavity. The two clamp shells are respectively provided with an engaging claw and an engaging groove. A connector prefabricated component including the clamp includes a connecting pipe fixed in the clamp body, wherein the accommodating cavity is provided with a sealing component for sleeving pipe opening. During construction, a straight pipe to be connected is inserted into the sealing component. Then the clamp body is tightened, and the sealing component tightly presses on a pipe body of the straight pipe to achieve sealing.

A system coupled to a pipeline includes a first portion and a second portion coupled to the first portion by an over-center latch and a secondary adjustment mechanism such that a diameter of the system can be adjusted independently by either the over-center latch or the secondary adjustment mechanism. The first portion may be coupled to the second portion by a ratchet mechanism. The system may include a service saddle or a tapping sleeve. The system may be coupled to a water main.
