Threaded assembly

A threaded device comprising a member having an externally threaded portion,

• a longitudinally extending groove formed in said portion,
• a nut having an internal thread positioned on said member,
• said nut having an inwardly opening annular channel and an annular organic plastic insert positioned in said channel engaging said externally threaded portion,
• an elongated locking element operatively interposed between said member and said nut,
• said locking element being positioned in said groove and constructed to prevent the angular displacement of said nut relative to said member,
• said locking element having a greater dimension in the radial direction than the depth of said groove whereby said locking element extends radially outwardly beyond the circumference of said externally threaded portion,
• said plastic insert engaging said locking element and constructed to prevent the longitudinal displacement of said locking element relative to said nut,
• said locking element having a generally channel shape defined by a base portion and a pair of parallel flange portions,
• said flange portions each having an inclined surface in wedged engagement with said plastic insert,
• said inclined surfaces causing the deformation of said plastic insert,
• at least one of the edges of said inclined surfaces being bent outwardly to enhance the retaining effect of said wedged engagement between said locking element and said plastic insert.
