ABSTRACT:
A connector for corrugated tubing, such as electrical conduit, provides easy installation and has superior resistance to pull out as well as high impact strength. The connector has a body with two slots on each side and a U-shaped locking element which snaps over the corrugated tubing. The locking element locks onto two portions of the circumference of the tubing, substantially symmetrically on both sides.
