A quick-release retaining device for securing a faceguard to a helmet shell. A selectively engageable latch structure maintains the retaining device in a closed condition. When the retaining device is urged to the open condition, the faceguard may be moved away from a wearer's face. The device is biased in the closed condition by a C-shaped clip, and has a sliding-bar feature for additional securement. The sliding bar is further secured by a locking pin.
