Equipment for injections comprising a syringe and matching needles. The syringe includes a piston, a body with a handle and a means to couple a matching needle. The said needle includes a body having an additional coupling means to the syringe coupling means, in which is fixed a tubular needle. The double ended needle has a main portion for the performance of the injection and a secondary portion to perforate the sealed lid of an ampoule. The body of the needle extends to form a tubular portion to receive an ampoule and the additional coupling means for coupling to the syringe is located at the distal extremity of the needle body. This avoids any possibility of injury of the operator during the coupling of the needle to the syringe, and of needle or syringe contamination during possible temporary removal of the needle from the syringe.
