Device for moulding thermoplastic containers by the blow moulding of preforms, comprising a mould ( 1 ) and a blowing assembly ( 2 ) with a nozzle ( 16 ) that can move axially between a raised position and a blowing position in fluid connection with a preform supported in the cavity of the mould. The half-moulds ( 3 a, 3 b) of the mould bear respective parts (Aa, Ab) together forming a male element (A) bordered by a wall ( 12 ) inclined towards the nozzle. The blowing assembly bears a female element (B) formed by a clamp ( 26 ) having an internal wall ( 30 ) complementary to the wall of the protuberance. In the blowing position, the cooperation between the male and female elements (A, B) locks the upper part of the closed mould.
