1. Penetrating projectile provided at least with a body (4) made of a composite material and a metal nose (2) arranged at the front of said body (4), and a connecting element (1) which is arranged so as to attach said metal nose of said penetrating military projectile (3) to said body (4), said conn
1. Penetrating projectile provided at least with a body (4) made of a composite material and a metal nose (2) arranged at the front of said body (4), and a connecting element (1) which is arranged so as to attach said metal nose of said penetrating military projectile (3) to said body (4), said connecting element (1) having a longitudinal axis (10), the portion (12) of said connecting element (1) intended to be attached to said body (4) comprising at least: an annular stop (13, 23) which is centered relative to the longitudinal axis (10) and is intended to come into contact with an edge (14, 24) of said body (4) made of a composite material for transmitting an axial compression;a longitudinal extension (15, 25) which is defined from said stop (13, 23), comprises a contact face (16, 26) and has a shape and a diameter which are adapted to said body (4), such that the contact face (16, 26) of said extension comes laterally into contact with a peripheral surface (17, 27) of said body, wherein said longitudinal extension (25) has a diameter which is adapted to said body (4) so as to be able to come laterally into contact with a radially inner face (27) of said body; andan annular lip (22) which is attached to the outer edge of the stop (23) and is longitudinally arranged opposite said longitudinal extension (25) so as to be able to come laterally into contact with a radially external face (28) of said body (4),wherein the contact face (16, 26) of said longitudinal extension (15, 25), which face contacts the body (4) when said body (4) and said connecting element (a) are assembled, is provided with at least one channel (21), andwherein, when said body (4) and said connecting element are assembled:(A) said channel (21) defines a gap between the contact face (16, 26) and the longitudinal extension (15, 25), and(B) the contact face (16) contacts the body (4) longitudinally forward of and behind said at least one channel (21). 2. Projectile according to claim 1, wherein longitudinal extension (15) has a diameter which is adapted to said body (4) so as to be able to come laterally into contact with a radially outer face (17) of said body. 3. Projectile according to claim 2, wherein said stop (13) comprises at least one contact surface (13A, 13B) in a general radial direction. 4. Projectile according to claim 3, wherein said stop (13) comprises a plurality of contact surfaces (13A, 13B) which succeed one another in the radial direction. 5. Projectile according to claim 3, wherein at least one contact surface (13A) is located in a plane which is radial with respect to said longitudinal axis (10). 6. Projectile according to claim 3, wherein at least one contact surface (13B) is of a conical shape which extends outwards towards the rear. 7. Projectile according to claim 1, wherein the radially successive walls of said projectile (3) in the region of the connection are such that the rigidity thereof under pressure increases radially outwards. 8. Projectile according to claim 1, wherein said connecting element (1) is arranged so as to attach the metal nose (2) to the body (4) made of a composite material. 9. Projectile according to claim 8, wherein said connecting element comprises, in the region of its front portion, connecting means which allow it to be attached to the metal nose. 10. Projectile according to claim 8, wherein the rear portion of the metal nose (2) comprises said connecting element (1). 11. Projectile according to claim 1, wherein the gap extends the longitudinal distance of the channel. 12. Projectile according to claim 1, wherein the connecting element comprises metal.
