The 22-year-old, whose career has been derailed by personal challenges, trained with Usuthu for a few weeks before penning a two-and-a-half-year contract with his former club.
"We've signed Konqobe with conditions," Sokhela confirmed at a press conference in Durban on Wednesday.
"We've given him six months of proving himself to the club then after that we will take it from there."
Sokhela believes Konqobe has the ability to play for Bafana Bafana and hopes the ex-Chippa United defender has learnt from his mistakes in the past.
"We believe in Konqobe, a very young player, we couldn't let him go," Sokhela said.
"We've signed him and also spoke to him to look at the bigger picture, which is his future. We hope he has learnt his lesson and will use this as an opportunity to save his career. We told him that this could be his last chance in football.
"If he can just focus on his talent we can safely say Bafana has another top defender in him."
Meanwhile, Sokhela indicated veteran striker Mabhuti Khenyeza may be considering retirement at the end of the season.
"Khenyeza has indicated the option of taking another step in his career. We are not sure as yet, but I can safely say he will definitely leave us."
