Set of a basic tube-shaped body (10) and a tube-shaped lid (20), which are open on a distal side (12, 22), and which are designed to be connected to each other by means of a socket connection and that they form a capsule (30) to contain an amount of medicament when said capsule is formed, where at least one notch (13) is disposed on an outer surface of the basic body (10), where at least one protuberance of fixing (23) on an inner surface of the cover (20), which is designed so that the notch (13) receives it without strike on the outer surface of the basic body (10) in order to achieve a fixed fitting connection, and wherein an inner diameter of the fixing boss (23) of the inner surface of the cover (20), in the position of an area of the fixing boss (23) located mostly inwards is smaller than an outer diameter of the notch (13) on the outer surface d the basic body (10), in the position of an area of the notch (13) located mostly inward, and where at least one retaining protuberance (24) is disposed on the inner surface of the lid (20), in a position closer to the open distal side (22) of the cover (20) than the fixing protuberance (23), designed to be received in such a way that it can be released in the notch (13) on the outer surface of the basic body ( 10), in order to achieve a fitting connection capable of being released, where an inner diameter of the retaining protuberance (24), in the position of an area of this protuberance (24) located mostly inward, is greater than an inner diameter of the fixing protuberance (23), in a position of an area of this protuberance (23) located mostly inward, and is larger than the outer diameter of the notch (13) on the outer surface of the basic body ( 10), in a position in the notch area (13) located mostly inwards.Conjunto de un cuerpo básico con forma de tubo (10) y una tapa con forma de tubo (20), que están abiertos en un lado distal (12, 22), y que están concebidos para ser conectados entre sí mediante una conexión d
