hub portion 23 is supported relative to the recess member 22 by several ribs 26 uniformly distributed about the circumference the open side of the semi spherical recess member 22 is closed off by a lid 27 during casting of the concrete wherein the closing position is provided by positive locking engagement of the annular projection 28 performed on the lid 27 which can be elastically clamped in the opening area of the recess member the external side of the lid 27 has several elastic indicator pins 29 which during smoothing of the cast concrete will fold over and after smoothing will stand up again because of their own elasticity and thus indicate at which position a transport anchor is positioned in the concrete the shaft portion 12 of the anchor shaft 11 which can be embedded in the concrete comprises a support 30 which is formed of a receiving box 31 on which a support disc 32 is secured which is connected to the shaft portion 12 to be embedded in the concrete while the anchor shaft 11 with its shaft parts 12 13 the engagement head 16 and the support disc 32 can be formed as a monolithic part of a metallic material such as for example steel the support 30 as well as the recess member 22 the shell parts 17 and 18 and also the lid 27.
