A hose clamp includes a clamp main body including a ring portion and a pair of knob portions; and a holder. The holder includes a main body portion, a pair of holding walls, and an operation portion. An inner surface on a distal end side of one holding wall includes a protrusion that protrudes more largely inward than an inner surface on a distal end side of other holding wall. And in a state where the pair of knob portions are close to each other, a distal end of one knob portion in a peripheral direction is engaged with the inner surface of the one holding wall, and the other knob portion is engaged with the inner surface of the other holding wall, so that the ring portion is kept in a diameter-increased state.

A flush device including: a first housing provided with a first flow path; a second housing provided with a second flow path, the second housing being coupled to the first housing; a flow control device including a protrusion and a through hole connecting the first flow path to the second flow path in fluid communication; and an elastic member provided around the base of the flow control device to seal off a space between the first and the second flow paths. The elastic member is deformed to further connect the first and second flow paths in fluid communication. The first housing has an inner periphery provided with fitting receiving portions each being fitted to each of the fitting projections of the protrusion. According to this structure, the flush device can discharge a chemical liquid at a flow rate close to a defined amount.

A spring clamp with integrated installation and removal capability allows a user to install or remove the spring clamp safely using common shop tools or by hand. The spring clamp includes two tangs with a fastener extending between them. The fastener may be used to draw the tangs together or apart, to thereby open or close the spring clamp, and to safely change the potential energy of the spring clamp. The user may turn the fastener or a nut on the fastener using common shop tools or by hand to expand the spring clamp so that it can be slipped over a hose and to allow the spring clamp to tighten around the hose.

A profiled clamp for assembling on pipe ends, having a first half-shell and a second half-shell, each of which has a clamping head at a first end and a connection geometry at a second end for releasably connecting the second end. The clamping heads are connected to a clamping element, and at least one of the two half-shells can be tilted relative to the clamping element. A spring element is arranged in the region of the clamping heads, said spring element pushing the second ends of the half-shells apart under pretension. Contact regions of the spring element can be positioned on the pipe ends in a frictionally locking manner when connecting the two ends.

A clamp serves to fasten a shield member to a tubular portion of a shield shell using the elastic restoring force of the clamp. The clamp includes an annular clamp body and a pair of tabs. The tubular portion includes a tubular outer contour having two straight sections and two curved sections in a cross-sectional view. The clamp body includes a straight corresponding section corresponding to one of the straight section of the tubular portion and curved corresponding sections corresponding to the curved sections. The straight corresponding section is configured to bend less easily than the curved corresponding sections.

The disclosure relates to a spring clamp, having a clamp band and a positioning device for pre-positioning the spring clamp on a hose end of a hose. The positioning device having a support band and a contact region, and the support band having. The positioner having a fixing means arranged at the end of the support band, and the support band having a retainer at another end of the support band. A web is formed in the support band between the contact region and the positioner. The support band has at least two regions in the region of the positioner, the first region extending from the web away from the clamp band and the second region extending substantially perpendicularly from the first region.

A clamping arrangement includes a clamp member and an elastomeric member. The clamp member is operative in a first orientation having a first inner diameter and a second orientation having a second inner diameter. The first diameter is greater than the second diameter. The elastomeric retaining member is carried by the clamp member and is operative to temporarily retain the clamping arrangement to a first tubular member having an outer diameter less than the first inner diameter when the clamp member is in the first orientation.
