Mechanical assembly (1) for the connection between a first modular element (3) and a second modular element (6) of telescopic poles for practicing sport, spare time activities and the like, said first modular element (3) having a first diameter (D1) and said second modular element (6) having a second diameter (D2), lower than said first diameter (D1) and being slidingly coupled with said first modular element (3) in such a way as to axially protrude from said first modular element (3) at an end (4) of said first modular element (3), said mechanical assembly (1) comprising a grasping device (2;
- 51), fixed to said first modular element (3) at said end (4), and being characterized in that it comprises a cursor (5) operable by the user, axially movable along said first modular element (3) and cooperating with an elastically yielding portion (7;
- 52), belonging to said grasping device (2;
- 51) and protruding from said end (4) of said first modular element (3), in order to set said elastically yielding portion (7;
- 52) between a rest position, in which said elastically yielding portion (7;
- 52) is released and said second modular element (6) is free to slide with respect to said first modular element (3), and an operating position, in which said elastically yielding portion (7;
- 52) is compressed by said cursor (5) in such a way to block the movement of said second modular element (6) with respect to said first modular element (3).
