A hose clamp includes an open ended ring body having a first engagement pin located at one end portion, a second engagement pin located at another end portion, and a retaining clip located adjacent the first engagement pin; and a connecting lever detachably attached to the ring body, and including a lever body having a first pivot notch located on one end, a second pivot notch spaced away from the first pivot notch, and a clipping slot located at another end. The first notch of the lever is connected to the first engagement pin of the ring, and the second notch is connected to the second engagement pin of the ring. When the lever is rotated relative to the ring body, the first notch pivots around the first engagement pin and the second notch of the lever pulls the second engagement pin around the first engagement pin.

The disclosed connector provides at least one female side with a sealing array comprised of first sealing member, a spacer, and a second sealing member that are all aligned to receive one end of an inserted part. A toolless retainer is positioned between the seals and the opening of the female side. The toolless retainer array has at least three appendages that extend outwardly for a distance and fold back inwardly to define three holders for retaining the inserted part. The seals are compressible and the spacer is non-compressible. The preferred connector has two female sides with toolless connectors.

A coupling device for coupling flanges of two pipes includes a chain assembly and a positioning mechanism. The chain assembly includes plural connecting pieces pivotally connected one by one by pivot members. The connecting pieces at two opposite ends of the chain assembly are defined as a first connecting piece and a second connecting piece. A first pivot member is arranged at the free end of the first connecting piece, and a second pivot member is arranged at the free end of the second connecting piece. The positioning mechanism includes a first portion and a second portion pivotally connected. The first portion is pivotally connected to the first pivot member or the first connecting piece, and the second portion is detachably positioned to the second pivot member. The first portion is rotatable between a release position and a fixed position relative to the second portion.

A clamping device for securing an accessory to a pole is disclosed herein. The clamping device includes a first clamp component formed from bent wire, the first clamp component configured to partially circumscribe a pole, and including at least one offset portion for defining an accessory receiving space between the first clamp component and a sidewall of the pole; a second clamp component rotatably coupled to the first clamp component, formed from bent wire, and configured to partially circumscribe the pole; and a handle component configured to couple the second clamp component to the first clamp component. When the handle component is rotated in a first tightening direction, the first clamp component and the second clamp component are brought into secure engagement about the circumference of the pole. When the handle component is rotated in a second loosening direction, the clamping device is capable of being disengaged from the pole.

An improved dryer exhaust vent assembly for a clothes dryer is disclosed. The assembly includes an exhaust pipe having a variety of features on its external surface that are constructed and arranged to provide a more secured and easier to obtain engagement with commercially available or customized vent tubing. The assembly may also utilize adjustable band clamps or lever actuated collar clamps to further secure engagement of the vent tubing to the exhaust pipe.

A hose connector apparatus for quick and easy dripless hose connection includes a first connector having a first inner end, a first outer end, and a first sidewall. The first outer end attaches to a first hose. The first inner end has a receiving cavity. A male clamp bracket is pivotably coupled to the first sidewall. A female clamp bracket is pivotably coupled to the male clamp bracket and has a female bracket distal end. A second connector has a second inner end, a second outer end, and a second sidewall. The second inner end has a protrusion portion slidably engageable within the receiving cavity of the first connector. The second outer end attaches to a second hose. A pair of locking pins is coupled to the second sidewall to selectively engage the female bracket distal end of the female clamp bracket.

At least one adjustable clamp device is disclosed that includes a catch member, a base member, a latch member, and a fine adjustment mechanism and is designed to clamp to a targeted object in a secure fashion. At least one quick release clamp device is disclosed that includes a catch member, a base member, a latch member, and a quick release mechanism and is designed to clamp to a targeted object in a secure fashion and to be quickly removable from the targeted object. At least one method for using the adjustable clamp device is disclosed that includes: wrapping an adjustable clamp device around a targeted object; placing a tool around the adjustable clamp device; squeezing the tool and thereby squeezing the adjustable clamp device around the targeted object; and causing the latch member to operably connect to the catch member in a locked position.
