摘要:
A flexible coupling device including a flexible metal rod or wire within a flexible tube which can be removably secured through the aligned bores of the pieces. The pieces are held in a fixed longitudinal relationship using the axial tension created by the flexible coupling device while still permitting relative rotation between each of the pieces. The flexible metal rod or wire is secured through various mechanism which include radial angular ridges in the interior of the flexible tube and a retaining post having radial angular ridges that interlock with the ridges in the flexible tube such that, as the post is inserted into the flexible tube, the post ridges and the tube ridges interlock to secure the flexible tube. In addition, radial angular ridges on the exterior of the flexible rod interlock with a retaining post having an interior bore with corresponding radial angular ridges as the flexible rod is inserted into the retaining post. The flexible rod can be pulled through the retaining post such that the excess of the flexible rod can be trimmed once it is secured.

A hand tool having a tool head and a handle is provided with a self-locking wedge embedded within said handle to effect a secure interconnection between the wedge, the handle and the tool head. The self-locking wedge is a single multielement member of high shear strength having a tapered central body and a plurality of integral wedge-shaped side arms intersecting the central body and projecting outwardly from opposite sides thereof. At least one of the side arms extends from the central body for a greater distance on one side thereof than on the opposite side thereof. Locking shoulders projecting from the central body are disposed inwardly of the side arms and cooperate with the side arms to interlockably retain the resilient grained structure of the handle and restrict removal of the wedge therefrom.

An end connector for attachment to a tubing end including a housing having a first aperture therethrough with a predetermined internal periphery and a plug member having a predetermined external periphery for cooperative engagement with the end of the tubing and the internal periphery of the first aperture of the housing, the plug member releasably retaining a portion of the end of the tubing between the external periphery of the plug member and the internal periphery of the first aperture of the housing to prevent removal of the tubing from the housing when the tubing is subjected to tension in a desired direction.
