  The recent data on the transverse single spin asymmetry
$A_{UT}^{\sin(\phi_h+\phi_S)}$ from HERMES and COMPASS Collaborations are
analysed within LO parton model with unintegrated parton distribution and
fragmentation functions. A fit of SIDIS data from HERMES Collaboration is
performed leading to the extraction of favoured and unfavoured Collins
fragmentation functions. A very good description of COMPASS data is obtained.
BELLE $e^+e^-$ data are shown to be compatible with our estimates based on the
extracted Collins fragmentation functions. Predictions for
$A_{UT}^{\sin(\phi_h+\phi_S)}$ asymmetries at JLab and COMPASS operating on a
proton target are given.
