Abstract

2133341 9319995 PCTABS00027 A sealing system of the type in which a locking pin is received in a cavity containing a tooth that cooperates with the pin to prevent withdrawal of the pin. The object of the invention is to provide this type of seal but which is at the same time both of high security and simple to manufacture. In the system of the invention, the cavity (2) has two openings (14, 16) adjacent to each other and separated by the base (17) of the tooth (18). The cavity is otherwise totally closed and its inner wall (21), which extends to the bottom of the cavity, is curved under the base (17) of the tooth. This permits manufacture using an injection mould having a plate (39) provided with a fixed part (40) and a part (41) rotatably mounted on the fixed part to define therebetween the male mould portion for moulding a cavity with a tooth. An actuator (42) serves to rotate the rotary part (41) during opening of the mould, the rotary part (41) having a curved surface (52) corresponding to the curved part of the inner wall (21) of the cavity.
Security seals and devices incorporating the new sealing system are also described.
