A system for organizing elongated objects (such as wires, cables, pipes, hoses, ducts, tubing, and other similar items) into bundles to create a more uniform, neat and functional arrangement is disclosed. The system includes a fastener adapted to extend along the length of an elongated object. The fastener provides a continuous attachment to another elongated object or to another object for a distance along the length of the elongated object. The fastener is preferably integrated with the structure of the elongated object, or alternatively, it may be applied as a wrap around the elongated object.

A coupling for connecting to an end of a tubular member is described. The coupling includes a housing that has a longitudinal bore for receiving the end of the tubular member. A collet is coupled to the housing and is disposed in the bore. The collet has a plurality of bendable fingers each of which has a projecting tooth to engage the end of the tubular member. An annular member is positioned around the plurality of fingers and is composed of a shape-memory material. The annular member is deformable in situ from a temporary shape to a permanent shape in which the annular member squeezes the plurality of fingers into engagement with the end of the tubular member.

A seal plate attachment (10) for earmuffs. The seal plate attachment (10) has a first (12) and second (30) portion including substantially flat surfaces (14, 32), outer perimeters (16, 34), and inner perimeters (17, 35) defining central openings (18, 36). The first portion (12) of the seal plate attachment (10) includes a first channel (20) extending around a section of the outer perimeter (16). The seal plate attachment (10) second portion (30) includes a rim (40), projecting inwardly from and extending around a section of the outer perimeter (34). The rim (40) of the seal plate attachment (10) second portion (30) forms a second channel (42) to oppose the first channel (20) on the seal plate attachment (10) first portion (12), allowing the second portion (30) to be slidable relative to the first portion (12). An improved earmuff design includes rigid earcup elements (11), a connecting band, and soft sealing elements (33) in combination with the seal plate attachments (10) for earmuffs.
