Abstract: A hose clip which can be tightened without a screw has an elongated band with a first end section which is formed with a closed slot for threading of the second end section therethrough. The end portion of the first end section has a pallet which engages one of a series of external teeth on the second end section to hold the band against expansion when the band surrounds and is tightened around an elastic hose. The end portion of the first end section extends radially outwardly and abuts against a back support which is an integral part of the first end section and is formed by looping the first end section radially outwardly adjacent to its end portion. The provision of the back support on the first end section enhances the versatility of the hose clip by enabling it to properly clamp smaller- or larger-diameter hoses without affecting the ability of the end portion of the first end section to remain in proper engagement with a selected tooth of the second end section.

Abstract: The present invention relates to a re-usable clamp constituted by a wound over strap of metal and comprising, near to the two ends of the strap, two radial folds or lugs projecting externally from the strap, the first of said lugs extending into a portion which follows the periphery of the clamp to constitute a sole-plate extending at least over the distance separating the two lugs, whereas the second lug is also provided with an extension which is substantially parallel to the periphery of the clamp and situated at a distance therefrom which is nearly equal to the height of one lug; the sole-plate extending from the first lug is provided with at least one asperity projecting externally from the strap and designed to cooperate, when the clamp is in a closed but untightened position, with the bearing part of a recess correspondingly provided in the strap behind the second lug.

Abstract: A muffler clamp wherein a retainer (22) is secured to a bracket (20) by nuts (24 and 26). The bracket (22) is provided with sections (38) and the retainer (22) has a flexible central region (40) such that the clamp can be tightly constricted about and secure exhaust system components in a range of sizes.

Abstract: A clamp and method enabling the tightness established by a clamp connection to be checked after installation. The clamp consisting of a band member formed with diametrically opposite eyelets which are engageable with a spanner tool, which in turn is engagable with a torque wrench to enable the tightness of the clamped connection to be checked by applying a torque sufficient to just slip.

Abstract: A crimp-type hose clamp wherein the ends of the clamp are joined in a double-layered top portion of the hat section of the clamp.

Abstract: A banding strap for attaching a heat shield to a muffler comprises a strap for encircling the muffler and heat shield, the strap including an underlying end segment and an overlying end segment, each including outwardly projecting shoulder sections providing abutments for crimping to interlock the end segments and tighten the strap around the muffler and heat shield. The outwardly projecting shoulder section in the overlying end segment forms an inwardly opening bight for receiving the outwardly projecting shoulder section in the underlying end segment. Each shoulder section includes an inwardly projecting indentation so that the indentation of one of the shoulder sections nests within the indentation of the other of the shoulder sections when the shoulder sections are engaged to prevent lateral misalignment of the end segments with respect to each other.

Abstract: A clamp structure with a clamping band and with at least one plastically deformable so-called "Oetiker" ear to be contracted to tighten the clamp structure about the object to be fastened; to assure a substantially smooth, gap-free transition in the circumferential direction within the area of overlap, for example, of an inner and outer band portion in the area of mechanical interlock or of an insert member and corresponding parts of the clamping band, a tongue portion is provided at each free end of the inner part which is adapted to engage in a corresponding aperture in the respective outer part when the ear is contracted.

Abstract: An insert ring for use with a hose clamp of the type provided with a circumferential band portion and with at least one ear projecting outwardly from the band and adapted to be deformed so as to tighten the clamp about the object to be fastened; the insert ring is so constructed and arranged as to prevent the portion of the insert ring underneath a respective ear from escaping outwardly into the opening within the area underneath the ear during contraction of the latter to thereby prevent any leakage within that area of the ear.

Abstract: Hose clamps are disclosed comprising a band, band section, or attachment to a band, which yields in a direction circumferentially of the band and which possesses a spring-like quality and/or action such that the clamp is essentially self-adjusting to compensate for thermal expansion and contraction of the assembly (clamp, hose and fitting), as well as for the aging or cold set which the hose undergoes, whereby a fluid-tight seal is maintained throughout the intended life of the assembly, without requiring the clamp to be re-tightened. The bands of the clamps are open-ended and of generally circular configuration and are provided with a tangentially located or oriented worm drive screw for closing the clamp and providing a greater and closer range of adjustment in closing the clamp. The clamps, in some cases, have incorporated therein a positive stop, whereby closure of the clamp can be limited to a specified or predetermined size or diameter.

Abstract: A hose clamp having a thickness that is maximum at its longitudinal center and is decreased symmetrically on each side of center progressively in proportion to the distance from the center until reaching end portions of uniform thickness. The band is bent into an annular shape with the ends overlapping. The ends are provided with holding portions projecting radially outward.

Abstract: A clamp structure with a clamping band having open ends adapted to be mechanically interconnected by outwardly extending hooks in an inner band portion operable to engage in corresponding apertures provided in an outer band portion; at least one plastically deformable ear is provided in the clamp structure for tightening the clamping band about an object to be fastened by plastic deformation of the ear; a substantially gap-free transition in the circumferential direction from the inner band portion to the ring-like configuration of the clamp structure defined by the clamping band is obtained by the use of a tongue-like extension at the free end of the inner band portion which is operable to engage into a tongue-receiving aperture or channel provided in the outer band portion.

Abstract: A clamp structure for clamping a hose-like member onto a circular support and capable of contraction from a larger to a smaller diametric dimension without loss of the circular configuration and without any internal projections, especially for use with relatively harder and thinner hose-like materials, in which the area underneath the ear is covered off during contraction to prevent leakage thereat and in which the open ends of the band can move relative to one another to change from the larger to the smaller diametric dimension while retaining a circular configuration where in engagement with the hose-like member.

Abstract: A clamp structure which includes a clamping band with open ends adapted to be interconnected and with an ear for tightening the clamping band about an object to be fastened by plastic deformation of the ear; the free ends of the clamping band are provided with arched surface portions, as viewed in transverse cross section, to provide outwardly extending, groove-like reinforcing embossments, and at least one end of the band is of tapered configuration, as viewed in the circumferential direction thereof, with the tapering side surfaces converging toward each other in the direction toward the respective band end so that the arched surface portion of the one band end is able to engage in the overlying arched surface portion near the other band end to assure thereby a continuously smooth, stepless internal configuration of the band during tightening thereof by contraction of the ear as the diametric dimension is reduced.
