An inflation device is provided with a connection head which comprises a housing with a receiving compartment. The receiving compartment is provided at one end thereof with a holding port, and an elastic block corresponding in location to one end of the holding port and having a through hole similar in construction to a fisheye hole. The through hole has a large diametrical end split with the holding port. The receiving compartment is further provided therein with a displacement member which has an inner end pressing against the elastic block, and an outer end located at the open end of the receiving compartment. The displacement member has a through hole split with the small diametrical end of the through hole of the elastic block, and an air guide hole extending from the periphery of the displacement member to communicate with the through hole. A slide member is formed of a press body located in the through hole, and a pliable strip extending through the through hole whereby the pliable strip is provided at a tail end thereof with a rack engageable with a gear which is pivoted to the outer end of the displacement member. The slide member is urged by an elastic member toward the inner end of the displacement member. The housing is further provided with a handle which is pivoted to the open end of the receiving compartment such that the handle can be swiveled to press against the displacement member.
