  Results on two-particle $\Delta\eta\Delta\phi$ correlations in inelastic p+p
interactions at 20, 31, 40, 80, and 158~GeV/c are presented. The measurements
were performed using the large acceptance NA61/SHINE hadron spectrometer at the
CERN Super Proton Synchrotron. The data show structures which can be attributed
mainly to effects of resonance decays, momentum conservation, and quantum
statistics. The results are compared with the EPOS and UrQMD models.
