Salford Red Devils are all-but mathematically safe in Super League for 2019 after Toulouse Olympique are beaten 44-10 at the AJ Bell Stadium.
This result puts them on 10 points with Leeds and two points clear of Toronto and Hull KR below them, with an unassailable points difference of 143.
Toulouse, whose promotion hopes look beyond them with just six points, fought back to 14-10 at one stage.
However, Salford's top-level experience proved key as they pulled clear.
The end-of-match score-line did not reflect the quality that Toulouse displayed throughout, and they were given a standing ovation by the home support, who were able to celebrate their return to the top tier next term.
Having lost at Championship side London Broncos last weekend to leave nerves jangling, Ian Watson's side ensured there was to be no further hiccups in the Qualifiers.
Jackson Hastings' suspension coincided with Salford dropping their 100% record, but he returned to star in this success, scoring one try - an eight-point try - and kicking seven goals.
His former Manly teammate Joey Lussick crossed before Toulouse scored two tries from Chris Centrone and Stan Robin in a flurry of points either side of the half-time hooter.
That gave the visitors hope of an upset, but Greg Johnson's double added to Niall Evalds, Kris Welham and Tyrone McCarthy tries quelled the French side's spirit and relieved the tension.
Retiring prop Luke Burgess kicked a late conversion to add to the carnival feel late on.
