The invention relates to an injection spigot (24), preferably for an injection head for injection drilling anchors with independent supply of a first and second supply component, wherein the injection spigot (24) has a housing (34) with an internal cavity which has at least one outlet opening for the outlet of the first and the second supply component. According to the invention, an advantageous improvement may be made, wherein the wall of the housing (34) has at least one first pre-determined breaking point (35) for forming a first inlet opening (36) for a first supply component under pressurisation and at a distance therefrom at least one second pre-determined breaking point (37) to form a second inlet opening (38) for a second supply component under pressurisation. The invention further relates to an injection head for drilling and pressing of drilling injection anchors in which an injection spigot (24) is inserted. |
