Принадлежит: HITCO Inc

A hinged clamp provides quick connection and disconnection of sections of fluid tubing. Some embodiments include a spring-loaded catch mechanism that enables the clamp to be loosely latched, and a winding mechanism that can retract the catch to a securely latched condition. Other embodiments provide a hinged shaft that pivots about an end of the upper clamp ring. A middle section of the shaft can be inserted into a slotted opening in the lower clamp ring, and the winding mechanism can move an engagement surface against the lower clamp ring to securely latch the clamp. An adjustment mechanism is included in these embodiments which can adjust the amount of winding required to engage the clamp. In various embodiments, less than one turn or less than one-half turn is required to engage/disengage the clamp. The clamp can be openable only just enough for insertion of flanged ends of the tubing sections.

A muffler, in particular a rear muffler, for an exhaust gas system of an internal combustion engine, in particular a motor vehicle engine, comprises a housing, in particular a housing having a jacket and two end walls, and comprises at least two pipes which are plugged into one another and which are at least partly received by the housing, in particular at least one inlet or outlet pipe which is in particular led through the jacket and which is connected to an inner pipe. The first pipe has a pipe piece into which a pipe piece, in particular an end section, of the second pipe is plugged. The pipe piece of the second pipe is provided with nubs at its outer boundary which engage into cut-outs provided in the pipe piece of the first pipe. In this respect, the cut-outs are dimensioned larger with respect to the nubs so that the end section is, on the one hand, fixed in the pipe piece but can be axially displaced to a limited degree relative to the pipe piece.
