9. The stick according to claim 1 , wherein,

the locking element ( 10 , 10 ′) is a clamp suitable for tightening around each cylindrical end portions of each two adjacent connecting tubular parts, the locking element ( 10 , 10 ′) comprising

a resilient tubular element ( 20 ) having a side wall ( 24 ) which defines a longitudinal cylindrical hole ( 28 ) for receiving the cylindrical end portion, said side wall ( 24 ) provided with a slit ( 32 ) which extends longitudinally in order to allow the resilient tubular element ( 20 ) to be selectively distorted in order to reduce the amplitude of the slit ( 32 ) and therefore the diameter of the hole ( 28 ) or to enlarge the amplitude of the slit and therefore the diameter of the hole, said slit ( 32 ) defining a first and a second edge of opposite side walls ( 32 a , 32 b ) having respectively a first coaxial opening ( 34 ) and a second coaxial opening ( 36 ),

pin means ( 40 ) anchored at one end in the first opening ( 34 ) in order to extend with the other end through the second opening ( 36 ), and

a lever arm ( 48 ) attached, in one of its ends, to the other end of the pin means ( 40 ) in a rotating manner, in order to move between a locking position of closure, wherein the lever arm ( 48 ) is in contact with the cylindrical end portion ( 4 ) in order to push the first and the second edge of the side walls ( 32 a , 32 b ) one towards the other, and a position of non-closure wherein the lever arm ( 48 ) is rotated away from the cylindrical end portion ( 4 ) in order to allow the slit ( 32 ) to widen ( 32 , 132 ),

said second edge of the side wall ( 36 ) comprising a cam surface ( 44 ), and said lever arm ( 48 ) comprising an eccentric knuckle joint ( 62 ) formed at one of the ends of the lever arm in order to touch the cam surface ( 44 ) and force the second edge of the side wall towards the first edge of the side wall when the lever arm is rotated towards the locking position.
