A flexible conduit fitting system includes a housing that defines at least part of a flexible conduit fitting, and a resilient clip supported by the housing. The flexible conduit fitting may include an aperture for receiving an end of a flexible wiring conduit. The resilient clip may have an engagement portion that extends into the aperture of the flexible conduit fitting to engage the generally corrugated outer structure of the flexible wiring conduit. The housing may be configured to support the resilient clip in a manner that allows the resilient clip to flex in a direction of movement of the flexible wiring conduit when the flexible wiring conduit is being inserted into the aperture and past the engagement portion, but to not substantially flex in the direction of movement of the flexible wiring conduit when attempting to withdraw the flexible wiring conduit from the aperture.
