Abstract
A device including a ring for linking a case and a projectile carrying a sealing band having a rear skirt providing low pressure sealing and a front rib lodged in a first groove in the projectile. The ring has a flared rear part connected with the case and a front part connected with the projectile by attachment means. The front part of the ring is lodged between the rear skirt of the band and the projectile and has a lip co-operating with the first groove or with a second groove in the projectile. A process for mounting the sealing band and ring to link the case and projectile includes sliding the sealing band and ring along the projectile in a single operation.
