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 corrugated band clamp is configured to effectively secure a sleeve around a pipe. The corrugated band clamp comprises an elongate member having a first lateral side and an opposing second lateral side. Typically, at least a portion of the length of the elongate member comprises a corrugated portion and at least a portion of the length of the elongate member comprises a non-corrugated portion. The corrugated portion of the elongate member enables the corrugated band clamp to effectively secure sleeves on pipes with non-parallel surfaces. In addition, applications of the corrugated band clamp system, methods of manufacture and methods of use are provided.

Disclosed are methods and apparatus that allow hand forces to easily cinch up and tighten a slotted band of a hose clamp to a position where a worm gear screw may then be used to firmly tightening the hose clamp around a hose or pipe. A cinching operation may be accomplished using a pawl apparatus provided at one end of a hose clamp having a centrally located downwardly facing tooth provided between a pair of oppositely positioned side walls which act as guides for receiving a slotted band of a hose clamp. A tightening operation may then be accomplished by turning the screw of a worm gear at the other end of the hose clamp. The hose clamp may be removed by releasing the pawl assembly or unscrewing the worm and gear screw.

The apparatus is a pawl clamping rachet device used with pipe or hose clamps when working in a tight space limiting access to advancing a slotted band needed for tightening the hose clamp. The apparatus having upstanding planar guide walls which guide a slotted band as the band is advanced through a gap with the band restrained in moving backwards by a pawl tooth having a spring function.

A hose clamp includes an annular band and a spring liner. The spring liner includes an annular body having a central axis. The annular body includes a first body section, a second body section, and a central body section connecting the first body section and the second body section. Various methods include applying the hose clamp to a substrate.

A clamp assembly has a clamp with a clamp band and a clamping device for clamping the clamping band and has a heat protection device with a housing and at least one insulating layer. The housing has a respective wall at each axial end face, the wall being divided into sections and protruding radially inwards, and the at least one insulating layer can be positioned between the walls of the housing. The clamp can be surrounded at least in some regions by the housing and/or the at least one insulating layer of the heat protection device, and the heat protection device is designed to be connectable to the clamp.
