1. A grip element for an exercise machine, comprising at least a tubular handgrip (2), forming at least one outer surface (3) to be gripped by the user's hand while performing exercises to develop muscles or the like, and having at least one substantially longitudinal through-channel (4) in which there will engage at least one flexible cable (5) connected to at least one resistant load of at least one exercise machine, wherein the handgrip (2) comprises means (6) for selective locking of the grip element in any position along the cable (5), the locking means having at least one contact surface (7) of the through-channel (4) designed to adhere by friction to the outer surface of the cable (5), when the grip element is manually translated and/or rotated in any direction in space, to prevent the handgrip (2) from sliding relative to the cable (5), wherein the handgrip (2) has a first end (2a) and a second end (2b) which are elastically flexible and define a first portion (8) and a second portion (8′) of said contact surface (7), respectively, said flexible ends of the handgrip being configured to bend with the cable (5), in order to generate adhesion of the first and second portions (8, 8′) of the contact surface (7) to the outer surface of the cable (5), for locking the cable relative to the grip element when exercises are being performed, wherein said longitudinal through-channel (4) is completely surrounded by the tubular handgrip whereby a movement of the handgrip consisting of a translation, rotation-translation or rotation in any direction in space not coinciding with the axis of the cable causes an adhesion of said first flexible end portion (8) and/or said second flexible end portion (8′) to the cable, and wherein the contact surface (7) is substantially located at least at one end opening of the through-channel (4). 2. The grip element according to claim 1, wherein the contact surface (7) comprises at least a first portion (8) and at least a second portion (8′) located at the opposite end openings of the through-channel (4). 3. The grip element according to claim 2, wherein the through-channel (4) has a rigid middle segment (9) having a substantially cylindrical shape. 4. The grip element according to claim 3, wherein the rigid middle segment (9) is formed by at least one sleeve (10) rendered integral and coaxial with the handgrip (2). 5. The grip element according to claim 1, wherein the handgrip (2) comprises at least one cylindrical helical spring (26) and a portion of rigid tube (27), to be gripped by the user's hand, rendered integral in such a way that it is coaxial with the spring (26) substantially at the centre, the contact surface (7) being formed by the inner surface of the spring (26) and being designed, when the grip element is manually translated and/or rotated, to bend at the ends and to adhere by friction to the cable (5), preventing the cable from sliding relative to the handgrip (2). 6. The grip element according to claim 1, wherein the selective locking means (6) comprise at least a first end housing (28) of the handgrip (2), communicating with the through-channel (4) and having at least a first hole (28a) for the passage of the cable (5) substantially coaxial with the through-channel (4), in which there engages, with radial play, at least a first bushing (28b) through which the cable (5) passes, the first bushing (28b) being designed to translate radially, due to cable (5) bending as a result of a manual action on the grip element, thus moving out of line relative to the first hole (28a) and locking the cable (5) between the first bushing (28b) and the first hole (28a). 7. The grip element according to claim 6, wherein the selective locking means (6) comprise a first end housing (28) and a second end housing (29), opposite each other, of the handgrip (2), respectively having a first hole (28a) and a second hole (29a) for the passage of the cable (5), the holes being substantially coaxial with and communicating with the through-channel (4), inside the first end housing (28) and the second end housing (29) there engaging respectively, with radial play, a first bushing (28b) and a second bushing (29b) through which the cable (5) passes, said first bushing (28b) and second bushing (29b) being designed to translate radially, due to bending of the cable (5) as a result of a manual action on the grip element, thus respectively moving out of line with the first hole (28a) and the second hole (29a) and locking the cable (5) respectively between the first bushing (28b) and the first hole (28a) and between the second bushing (29b) and the second hole (29a). 8. The grip element according to claim 7, wherein the first end housing (28) and the second end housing (29) are respectively formed by a first bush (30) and by a second bush (31), rigidly connected to the first end (2a) and to the second end (2b) of the handgrip (2), respectively forming a first pierced base (32) and a second pierced base (33) for the passage of the cable (5). 9. The grip element according to claim 1, wherein the selective locking means (6) comprise at least one radial sector (34), engaged in a respective radial through-seat (35) made in the handgrip (2) and communicating with the channel (4), forming at least one outer manual action surface (36) and at least one inner shaped surface (37), said radial sector (34) being manually movable, opposed by at least one return spring (38), from an inactive position in which the inner shaped surface (37) is retracted in the radial seat (35) and the cable (5) can slide freely in the through-channel (4), to a locking position in which the inner shaped surface (37) penetrates the through-channel (4), pressing the cable (5) against the channel (4) to prevent, by friction, cable sliding relative to the handgrip (2). 10. The grip element according to claim 9, wherein the selective locking means (6) comprise a plurality of radial sectors (34), engaged in respective radial through-seats (35) made in the handgrip (2) and communicating with the channel (4), forming respective outer manual action surfaces (36) and respective inner shaped surfaces (37), each of the radial sectors (34) being manually movable, opposed by a respective return spring (38), from an inactive position in which the inner shaped surface (37) is retracted in the radial seat (35) and the cable (5) can slide freely in the through-channel (4), to a locking position in which the inner shaped surface (37) penetrates the through-channel (4), pressing the cable (5) against the channel (4) to prevent, by friction, cable sliding relative to the handgrip (2). 11. The grip element according to claim 1, wherein the handgrip (2) is made of substantially elastically flexible material, the handgrip (2) comprising a first end (2a) and a second end (2b) which are elastically flexible and at which there are a first portion (8) of the contact surface (7) and a second portion (8′) of the contact surface (7). 12. The grip element according to claim 1, wherein the handgrip (2) is made of substantially elastically flexible material, the handgrip (2) comprising a first end (2a) and a second end (2b) which are elastically flexible and at which there are a first portion (8) of the contact surface (7) and a second portion (8′) of the contact surface (7). 13. The grip element according to claim 2, wherein the handgrip (2) is made of substantially elastically flexible material, the handgrip (2) comprising a first end (2a) and a second end (2b) which are elastically flexible and at which there are the first portion (8) of the contact surface (7) and the second portion (8′) of the contact surface (7). 14.
