The invention relates to a coil former (110) for a coil (100) of an electric machine (400). The coil former has a coil core (112) and a terminating wall (115) having a first edge (118) and a second edge (119). The first edge is arranged opposite the second edge, and the terminating wall is designed to retain a coil wire (120), which can be wound around the coil core, in a wound position. The terminating wall has a first retaining projection (130) and a second retaining projection (140), wherein the first retaining projection extends in an extension plane (117) of the terminating wall from the first edge in a first projection direction (131) along a first center axis (132) of the first retaining projection and the second retaining projection extends in the extension plane (117) of the terminating wall from the second edge in a second projection direction (141) along a second center axis (142) of the second retaining projection.
