A nuclear fuel assembly comprises a skeleton that constitutes the structure of the assembly and that holds a bundle of fuel elements at nodes in a regular array. The skeleton comprises two end pieces interconnected by guide tubes. The connection between each guide tube and the lower end piece comprises a peg formed with a coolant flow hole having a top portion fixed in the guide tube and a projecting bottom portion, which has a downwardly facing shoulder for bearing on the lower end piece, which passes through a passage formed in the lower end piece, and which is divided into a plurality of resilient fingers each having an upwardly facing shoulder for catching on the lower end piece.
