Eighteen-year-old Collins is a versatile player who can play up front, just behind the striker, wide right, wide left or in central midfield.
Collins, from Bridgwater, signed his first professional contract with Exeter in April 2016 having trained a number of times with their first-team the previous season.
He also made appearances in their under-21 and reserve team matches and has spent time on loan with Vanarama National League South side Weston-super-Mare.
Collins should be available for tonight’s fixture at home to Farnborough.
