A syringe with a barrel for holding a fluid medium includes a sealing cap that is put on the outlet end of the barrel. The barrel in the section that can be inserted into the cap has a first locking element on the outside. The sealing cap in the corresponding section has interactive second locking elements on the inside. The sealing cap can thus be put onto barrel with little force and thus less cracking occurs. To facilitate locking, the cap has a large number of second locking elements that are arranged peripherally. In each case, an expansion section is provided in the wall of cap between each pair of adjacent locking elements.
