Answer is: platelet plug

When platelets stick to each other and to the blood vessel they form a plug in the hole of the vessel. This process is called platelet aggregation.

Before the plug forms, a platelet will stick to the blood vessel (adhesion), change its shape and signal other platelets to come help (activation and secretion). Then they stick to each other (aggregation).
