A class of snap fasteners is described each of which includes at least one male and at least one female member. The female members have at least one socket portion which may be in the nature of a cavity in a hollow housing accessible by a fenestration in a face wall which is normally exposed or accessible, or may be in the nature of a through-hole in a substantially solid elongate bar member. The male members have at least one insert portion configurated and dimensioned to be receivable within an associated socket portion with relatively little clearance. Retainers are provided which limit free movement of the insert portions into and out of the socket portions. In the preferred embodiment, the retainers are in the nature of at least one protuberance or nipple at the fenestration or access opening to the socket portion which forms a local constriction of the fenestration area to provide an interference fit when the insert portion passes through the fenestration. By making either one of the portions or the retainers out of a resilient material, the insert portions can be snapped into engagement with the associated socket portions while maintaining the male and female members in substantially parallel planes throughout the joining operation. Other protuberances may be provided to improve the snap connection as well as to positionally stabilize the members once joined. The male and female members are provided with suitable connecting means for attachment to the parts to be releasably joined by the snap fastener, and are adapted to be gripped to permit the members to be separated without applying excessive stresses to the parts to be joined.

A fastener for releasably joining two associated parts to each other, comprising a female member having a first connecting means for connecting said female member to one of the associated parts, and having a socket portion; a male member having a second connecting means for connecting said male member to the other one of the associated parts and having an insert portion, said insert portion being dimensioned and configurated to be removably receivable within said socket portion with little relative clearance, said first and second connecting means being securely attached to the respective ones of said portions and being adapted to be gripped to disengage said portions without applying excessive stresses to the associated parts, said socket portion forming a substantially hollow housing having an aperture in a side wall and having fenestration means in a face wall of said housing for exposing the interior thereof, and said insert portion comprising a tab dimensioned and configurated to substantially correspond to the configuration and dimension of the interior of said hollow housing so as to be receivable therein by passage through said fenestration means, at least one of said portions being provided with retaining means in the form of a plurality of protuberances, some of which are on one side of said side wall projecting inwardly of said fenestration means and on the other side of said side wall projecting in a direction away from said fenestration means and in a direction of said second connecting means, so that said retaining means releasably retaining the other of said portions during engagement therebetween of said socket and insert portions, said insert portion being snappingly receivable into said socket portion by deforming at least one of said portions and said retaining means.
