The test specimen includes a web and at least one main flange connected to one end of said web. The device includes a body in which there is formed a housing which is shaped to house said test specimen transversally and which has a main bearing face against which one face of said web is intended to press; and a mobile clamp formed so as to press said web against said main bearing face. ## Claims ### Claim at position 1 1-12. (canceled) ### Claim 13 A device for the transverse retention of a longitudinal test specimen, comprising a web and at least one main flange connected to one end of said web, comprising: a body in which there is formed a housing which is shaped to house said test specimen transversally and which has a main bearing face against which one face of said web is intended to press; and mobile clamping means formed so as to press said web against said main bearing face. ### Claim 14 (depends on 13) The device as claimed in claim 13, wherein: said housing comprises a first additional bearing face against which one face of said main flange is intended to press; and said mobile clamping means for clamping said web are configured and arranged so that they press said main flange against said first additional bearing face. ### Claim 15 (depends on 13) The device as claimed in claim 13, wherein said mobile clamping means comprise: a moving part which has a contact face intended to press against another face of said web; and means for adjusting the intensity of the force applied to said web by said moving part. ### Claim 16 (depends on 15) The device as claimed in claim 15, wherein said adjusting means are in the form of at least one screw, passing through said body, which screw presses via one of its longitudinal ends against said moving part. ### Claim 17 (depends on 13) The device as claimed in claim 13, further comprising a removable cover configured and arranged to close off said housing. ### Claim 18 (depends on 17) The device as claimed in claim 17, wherein said test specimen comprises an auxiliary flange, connected to said main flange by said web, and said cover comprises additional moving clamping means formed to apply a retention force to one face of said auxiliary flange. ### Claim 19 (depends on 18) The device as claimed in claim 18, wherein said body comprises a second additional bearing face against which said auxiliary flange is pressed by said additional clamping means. ### Claim 20 (depends on 19) The device as claimed in claim 19, wherein said second additional bearing face is mounted so that it can move. ### Claim 21 (depends on 13) The device as claimed in claim 13, wherein said main bearing face is covered, at least in part, with a material that has a low coefficient of friction. ### Claim 22 (depends on 21) The device as claimed in claim 21, wherein said low coefficient of friction material comprises of polytetrafluoroethylene. ### Claim 23 (depends on 13) An apparatus for the mechanical characterization in bending of a test specimen comprising a web and at least one main flange connected to the end of said web, comprising at least two transverse retention devices as specified in claim 13, which retain the longitudinal ends of said test specimen. ### Claim 24 (depends on 23) The apparatus as claimed in claim 23, further comprising two supports which are connected to a fixed base and on which said transverse retention devices are respectively rotatably mounted. ### Claim 25 (depends on 23) The apparatus as claimed in claim 23, further comprising at least one additional transverse retention device positioned between the two end retention devices in the center thereof, and via which a bending force is applied to said test specimen.
