Abstract

An anchoring sleeve for retaining an electrical lead including a sleeve base and a locking member latchable to the sleeve base to lock the locking member to the sleeve base encircling the lead and engaging it around its full circumference. The locking member may be an arcuate member joined to said sleeve base by a hinge and pivotable to latch said locking member to the sleeve base. Alternatively the locking member may be a member formed separately from the sleeve base. The base may be provided with one or more C-shaped members to temporarily retain the lead prior to latching.

Claims

1. An anchoring sleeve for retaining an electrical lead having a circumference, comprising:
