Overhook clamp
Also known as Clamp Position — the canonical term used on this site.
Descriptive — overhook-based clamp guard
Overhook clamp is the compound descriptive name for the clamp guard — combining the overhook-grip element with the clamp position-name.
Etymology. “Overhook” specifies the closing-grip mechanism; “clamp” attaches the position-family canonical name. The compound predominates in instructional contexts that explicitly flag both elements.
Mechanics. The overhook closes the upper body while the leg pressure clamps the opponent — the closed-loop configuration limits the opponent’s posture options.
Cross-reference. “Overhook guard” and “body lock from guard” are alternate names. Full mechanical coverage on Clamp Guard.
