Cone penetrometer comprising: - a substantially tubular main body having a front end and a rear end, - a conical nose which is coupled to the front end of the main body, and - a cylindrical friction sleeve arranged around part of the main body, in such a manner that the main body and the friction sleeve delimit an annular clearance, in which a substantially sleeve-shaped force measurement element is accommodated concentrically with the main body and the friction sleeve, in which the main body comprises a shoulder with a stop face facing towards the front end, in which the friction sleeve comprises a shoulder with a stop face facing towards the rear end, in which the force measurement element has two end portions (64, 65) and a middle portion extending between them, and in which the end portions (64, 65) of the force measurement element have end faces (61, 62), characterized in that the force measurement element, in the axial direction, is retained only by the stop face which is directed towards the rear and arranged on the friction sleeve and by the stop face which is directed towards the front and arranged on the main body, wherein the stop faces (22, 52) of the main body respectively of the friction sleeve bear against the end faces (61, 62) of the force measurement element, such that the force measurement element is fixed without screw connections between the force measurement element and the friction sleeve and between the force measurement element and the main body. - a substantially tubular main body having a front end and a rear end, - a conical nose which is coupled to the front end of the main body, and - a cylindrical friction sleeve arranged around part of the main body, in such a manner that the main body and the friction sleeve delimit an annular clearance, in which a substantially sleeve-shaped force measurement element is accommodated concentrically with the main body and the friction sleeve, in which the main body comprises a shoulder with a stop face facing towards the front end, in which the friction sleeve comprises a shoulder with a stop face facing towards the rear end, in which the force measurement element has two end portions (64, 65) and a middle portion extending between them, and in which the end portions (64, 65) of the force measurement element have end faces (61, 62), characterized in that the force measurement element, in the axial direction, is retained only by the stop face which is directed towards the rear and arranged on the friction sleeve and by the stop face which is directed towards the front and arranged on the main body, wherein the stop faces (22, 52) of the main body respectively of the friction sleeve bear against the end faces (61, 62) of the force measurement element, such that the force measurement element is fixed without screw connections between the force measurement element and the friction sleeve and between the force measurement element and the main body. in which a substantially sleeve-shaped force measurement element is accommodated concentrically with the main body and the friction sleeve, in which the main body comprises a shoulder with a stop face facing towards the front end, in which the friction sleeve comprises a shoulder with a stop face facing towards the rear end, in which the force measurement element has two end portions (64, 65) and a middle portion extending between them, and in which the end portions (64, 65) of the force measurement element have end faces (61, 62),
