A capo that includes a clamping bar (1) which is intended to extend transversely over the fingerboard on the neck of a stringed instrument, and a tensioning device which includes a resiliently bendable tensioning strap (6) whose one end-part (2) is essentially flexurally rigid and connects generally perpendicularly with one end of the bar (1). The other end can be detachably connected to the other end of the bar (1) with the aid of a fastening means (7, 8, 9; 11, 12), so as to clamp the bar (1) securely against the fingerboard with a desired clamping force. The tensioning strap (6) is free-standing from bar in its non-tensioned memory state, and the one end-part of the tensioning strap is directed at its connection with the bar in a manner such as to diverge from the undersurface of the neck when no tension is applied to the strap (6). The tensioning strap has in a non-tensioned state a memory form in which the strap holds the components of the fastening means (7, 8, 9; 11, 12) close to their mutual position of engagement. The tensioning strap (6) is pre-formed such that when initially tensioned, it will contact the neck in a peripheral region that lies beyond the symmetry plane of the neck (6) from a corner angle (3) between the one bar end and one end-part (2) of the strap, whereby a force resultant to the area of contact of the strap with the neck (6) strives to hold the neck corner (4) in engagement with the corner angle (3) and therewith tighten or tension the capo. |
