Holding needle comprising gripping cheeks

A method of manufacturing a take-off needle comprising the steps:

• manufacturing an assembly comprising a holding body attached to one or more hollow lances and to two spigots, wherein each spigot is connected to and projecting from the holding body in a direction selected from the group consisting of transversely and obliquely;
• forming two half shells to fit over the assembly, wherein the two half shells extend between the two spigots to a proximal end of the holding body, each half shell having an internal form which mates with an external form of the holding body, wherein the two half shells together mate with the external form of the holding body, and extend in a longitudinal direction from the two spigots to a vicinity of a proximal end of the one or more hollow lances;
• the half shells each have an outer surface, each outer surface having a flange fixed to it by a spacer wherein each of the flanges is arcuate so as to be bowed towards the holding body, and
• mounting said half-shells onto the holding body so that the spigots project from between the flanges.

A method of forming a dual take-off needle comprising the steps of

• producing an assembly formed from a holding body having two hollow lances, a first main hollow lance adapted for the passage of liquid to be taken off of a container containing the liquid and a second venting hollow lance adapted to inject air into the container containing the liquid to be taken off and two spigots extending from the holding body, wherein each spigot is connected to and projecting from the holding body in a direction selected from the group consisting of transversely and obliquely;
• producing two half shells to fit over the assembly, wherein the two half shells extend between the two spigots to a proximal end of the holding body, each half shell having a flange fixed to the respective half shell by a spacer, each half shell having an internal surface which mates with an exterior surface of the assembly;
• and
• attaching the half shells to the exterior surface of the assembly.
