Patent ID: 6840705

Claim:
An assembly of two parts, one of which is fixed and the other of which is removable, the assembly being of the type including automatic locking and unlocking means for securing the removable part to the fixed part, said unlocking means being mounted on the removable part and being integrated inside it, and in which the removable part has a male end adapted to be received in a complementary female end of the fixed part, the male end snap-fastening against a stop latch inside said female end, said latch being urged resiliently by a spring into a position in which it locks the male end in the female end, which male end has a cone mounted at the end of the removable part in such a manner that, while the cone is being inserted into the female end, the latch can slide over the cone, thereby compressing its return spring, wherein the cone presents a flat, wherein the male end has a segment placed behind the cone and presenting a recess for receiving the latch, said recess opening in register with the cone, and wherein the cone is movable relative to the segment between a locking position in which the flat is out of alignment with the recess, thereby holding the latch captive in the recess, and an unlocking position in which the flat is in alignment with the recess, thereby allowing the latch to be released.
