The invention refers to a ball clamp bolt used to provide a detachable connection between two plates each of which has a hole. The ball clamp bolt has a grip, a positioning bolt which can be shifted relatively to the grip against the force of a first spring, this positioning bolt having a locking piece at its free end. The locking piece can be adjusted by means of a plunger which can be shifted relatively to the positioning bolt from a locking position preventing the passage of the positioning bolt through the holes to a release position extending into a recess in the plunger and permitting such passage. Between the plunger and the positioning bolt there is a second spring. The recess has on the side facing the locking piece a sidewall inclined to the axis of the plunger on which the locking piece can slide into the recess.
