<p>A handle is provided for hand tools with interchangeable heads. The handle has a tube (1) which has a cross-section with which is defined by a curved triangle which has one of its vertices in the lower position, and which is delimited by curvo-convex sides (2) which are connected by rounded edges (3). The tube (1), in its front opening, receives inside it a locking element (4) whose cross-section is the same as that of the said tube (1) and is adjusted by sliding it with respect to the inside of the tube. The tube (1), in addition to the channel (5) for inserting the flat rod (6) and the smooth shank of the interchangeable head, has on its upper face a vertical blind cavity (7) which, on its front wall, communicates with the said insertion channel (5), and in which a locking piece, or immobiliser (8), moves with vertical displacement, which immobiliser is mounted against a spring (9) which causes it to adopt an upper position in which a suitable tooth (10) is housed across a window (11) of the said flat rod (6) of the interchangeable head. The immobiliser (8) is capable of adopting a lower position, against the said spring (9), in which the said tooth (10) is outside the said window of the flat road (6), and wherein the immobiliser (8) faces at the top an opening (12) of the said tube.
