Abstract: A clamp for a winged needle that functions simultaneously as a protector and as a clamp and that does not require a recapping operation is provided. The clamp includes a flexible curved portion 1 including a tube insertion hole 11 provided on the proximal side and an upper member 2 and a lower member 3 connected via the curved portion 1 and which can be engaged on the distal sides thereof. The clamp is adapted to pressurize the tube 44 when the upper member 2 and the lower member 3 are engaged, and to generate a clearance through which at least a wing 4 can be introduced when the upper member 2 and the lower member 3 are not engaged. The upper member 2 or the lower member 3 is provided with a space 32 in which the needle 41 and the hub 42 can be stored.
