Clamp for fastening a contact wire to a dropper wire, comprising: - two clamp halves (11, 12), - a connection facility for connecting the two clamp halves (11, 12), wherein the clamp halves (11, 12) comprise: - a first end in each case, wherein the first ends, in a connected state of the clamp halves (11, 12), converge towards one another in order to engage into clamping grooves of a contact wire, - a second end in each case, wherein the second ends, in a connected state of the clamp halves (11, 12), interlock such that they provide a loop for a suspended connection of a dropper wire to the clamp, - a contact area facing the other clamping half (11, 12) in each case, wherein the contact areas, in a connected state of the clamp halves (11, 12), generate a clamping connection between the clamp and the dropper wire fed between the clamp halves (11, 12), characterised in that the width of the clamp transverse to the longitudinal direction of the contact wire in the region of the first end is less than or equal to 120 % of the horizontal width of the contact wire to be connected, in particular less than 2 mm wider than the contact wire to be connected, and the width of the clamp transverse to the longitudinal direction of the contact wire from the first end up to the edge of the second end is less than or equal to 120 % of the horizontal width of the contact wire to be connected, in particular is less than 2 mm wider than the contact wire to be connected. - two clamp halves (11, 12), - a connection facility for connecting the two clamp halves (11, 12), wherein the clamp halves (11, 12) comprise: - a first end in each case, wherein the first ends, in a connected state of the clamp halves (11, 12), converge towards one another in order to engage into clamping grooves of a contact wire, - a second end in each case, wherein the second ends, in a connected state of the clamp halves (11, 12), interlock such that they provide a loop for a suspended connection of a dropper wire to the clamp, - a contact area facing the other clamping half (11, 12) in each case, wherein the contact areas, in a connected state of the clamp halves (11, 12), generate a clamping connection between the clamp and the dropper wire fed between the clamp halves (11, 12), characterised in that the width of the clamp transverse to the longitudinal direction of the contact wire in the region of the first end is less than or equal to 120 % of the horizontal width of the contact wire to be connected, in particular less than 2 mm wider than the contact wire to be connected, and the width of the clamp transverse to the longitudinal direction of the contact wire from the first end up to the edge of the second end is less than or equal to 120 % of the horizontal width of the contact wire to be connected, in particular is less than 2 mm wider than the contact wire to be connected. - a first end in each case, wherein the first ends, in a connected state of the clamp halves (11, 12), converge towards one another in order to engage into clamping grooves of a contact wire, - a second end in each case, wherein the second ends, in a connected state of the clamp halves (11, 12), interlock such that they provide a loop for a suspended connection of a dropper wire to the clamp, - a contact area facing the other clamping half (11, 12) in each case, wherein the contact areas, in a connected state of the clamp halves (11, 12), generate a clamping connection between the clamp and the dropper wire fed between the clamp halves (11, 12),
