1. A sniffer probe for a leak detector for monitoring the leaktightness of an object to be tested by tracer gas, the sniffer probe comprising:
an end piece created in the form of a rigid tube;
a housing;
a connection member connecting the end piece to the housing; and
a sampling duct configured to sample a gas at a first end of the end piece,
wherein the connection member comprises a main body that is elastically deformable such that, when acted on by a force, the end piece is pivoted from an initial rest position to a deformed position and, when the force is released, the end piece returns to the initial rest position, and
wherein the main body is made of a single plastic or elastomeric material.
