Abstract: The invention relates to a foldable grip for mounting on an elongate object, such as the barrel of a portable weapon. The grip comprises an elongate grip section and a hinge which connects the grip section to the elongate object. For effecting the movement between a folded-in position and a folded-out position, the hinge consists of an oblique pin to be affixed on the elongate object and of an oblique hole formed in the grip section and cooperating with the pin. During the movement of the grip section between the folded-in position and the folded-out position, the grip section turns through essentially 90 degrees around an axis in the longitudinal direction of the grip section.
