1. A system comprising: a cannula comprising an interior lumen; a bone filler material delivery nozzle comprising a proximal end having a handle and an opposite distal end, the distal end being positioned within the interior lumen, the bone filler material delivery nozzle being configured for conveying bone filler material to a target location through the interior lumen; a retainer comprising gripping arms for coupling the bone filler material delivery nozzle to a proximal end of the cannula to prevent movement of the bone filler material delivery nozzle relative to the cannula, the retainer being spaced apart from the interior lumen; and a clamping element positioned between the retainer and the handle when in an assembled configuration, wherein the bone filler material delivery nozzle has a gripping region having a first dimension, gripping surfaces of the gripping arms having a default spacing of a second dimension, the second dimension being greater than the first dimension, the clamping element being configured to engage the retainer to move the gripping arms inward such that the gripping surfaces engage the gripping region.
