The on-loan Mamelodi Sundowns striker's 25th-minute strike from a Giorgi Nergadze pass was enough to separate the teams on a night where clear-cut goal-scoring chances were few and far between.
The opening ten minutes of the match were not very inspiring as both sides gave possession away far too often and there was a lack of quality in the final third.
First to have a chance at goal was Tuks striker Atusaye Nyondo, but he could not keep his effort from going past the upright inside the first 20 minutes. Shortly afterwards Geoffrey Massa saw his effort fly over the crossbar.
Five minutes later Swallows took the lead when Nergadze found Manqele inside the area and the in-form marksman beat Washington Arubi in goal.
Steve Barker’s men did not really trouble Greg Etafia and the teams went into the break at 1-0 to Swallows.
Manqele had the first real chance of the second half, in the 55th minute, but Washington Arubi saved the chance easily.
Massa had a chance to level at the far post on 68 minutes, but he could not keep his header down.
Swallows fashioned another chance in the closing stages of the match, but Manqele’s shot from a tight angle was way off target when a cross would have been a better option.
