A projectile includes an ejectable cup intended to protect a base of the projectile from propulsion gases, the cup including a wall surrounding the base and extending to a position where the edge of the wall is pinched between a seal surrounding the body of the projectile and a collar, including an annular part centered on a first cylindrical seat having a first diameter. The first seat is separated from a second seat by a shoulder, the face of which is oriented toward the rear of the projectile, a gripping means pressing the seal against the annular part, which causes the radial expansion of the seal, pressing it against the edge of the cup.
