A party of 20 players took part in a three-day Under-19s training camp last week and Redknapp insisted Tottenham's players were involved.
Tottenham were understood to have queried the need for the Football Association to take Steven Caulker, Andros Townsend, Ryan Mason and Dean Parrett to the tournament.
But Redknapp told Sky Sports News: "I had a word with the chairman and the kids were released."
He continued: "It's a great honour to play for your country and we wouldn't want to stop them from playing. It's important, whatever age group, whatever level, it's something you strive for.
"I have never stopped anyone from playing for their country wherever they are from. I always encourage that and this is no different. If they need the kids we will get it sorted out."
Redknapp's comments are clearly aimed at defusing any potential row between club and country.
The players were part of a squad that trained at Warwick University and they are scheduled for departure to Normandy on July 15. The tournament begins three days later and England's group involves Austria, Holland and France with the top pair joining two from Italy, Spain, Portugal and Croatia in the semi-finals.
Sir Dave Richards, the chairman of Club England, wrote to all clubs last month pointing out that they wanted "to prioritise player release in the Under-19s outside the competitive part of the season''.
A fortnight ago, the FA's director of football development, Sir Trevor Brooking, said that "tournament experience would be fantastic", although he feared there were "three or four at clubs who want to take them on pre-season trips".
Blackburn's Phil Jones and Aston Villa's Nathan Delfouneso are also wanted by the FA for the tournament. Jones is already an established member of the Blackburn first team while Delfouneso is expected to stake a claim for a regular slot in Villa's starting line-up. The pair would miss over two weeks of their club's pre-season preparations if they travelled with England.
